Introduction: How to Divide

Picture of How to Divide

Division is a core life skill. Calculating the fraction someone is owed or should receive — for instance when splitting a check or dividing the costs of a trip — is a mathematical challenge you are likely to encounter on an almost daily basis.

Long division sounds scary, but it’s not. This instructable will teach you how to find the answer to a division problem, also known as the quotient. It will also teach you how to solve division problems that have remainders. You won’t need a calculator, and you will be able to show your work. You’ll not only be able to complete any worksheet for school, you’ll always be prepared and confident when you have to split a check three ways.

Step 1: Things You'll Need

There are three different "methods" that I will be teaching you. To learn all of the methods you will need a pencil and lots of paper. You may also want to have a calculator to double-check your answers.

Step 2: Simple Division

The first method is simple division. Your answer will come out as a whole number.

1) Setup the division problem (84/7).
2) Divide 8 by 7 to get 1. Place this on top of the 8 and the division sign.
3) Multiply 1 and 7 to get 7. Place this under the 8.
4) Subtract 7 from 8 to get 1.
5) Carry down the 4.
6) Divide 14 by 7 to get 2. Place this on top of the 4 and the division sign.
7) Multiply 2 by 7 to get 14.
8) Subtract 14 from 14 to get 0.

The answer is 12!

Step 3: Simple Division With Remainder

This is the same as simple division except we add in the remainder.

1) Setup the division problem (10/3).
2) Divide 10 and 3 to get 3. Place this on top the 0 and the division sign.
3) Multiply 3 by 3 to get 9. Place this under the 10.
4) Subtract 9 from 10 to get 1. That is the remainder.

The answer is 3 r 1!

Step 4: Long Division With Decimal

This is similar to dividing with a remainder except you go a step further and have a decimal.

1) Setup the division problem (127/4).
2) Divide 12 and 4 to get 3. Put this on top of the 12 and the division sign.
3) Multiply 3 and 4 to get 12. Place this under the 12.
4) Subtract 12 and 12 to get 0.
5) Carry down the 7.
6) Divide 7 and 4 to get 1. Put this on top of the 7 and the division sign.
7) Multiply 4 and 1 to get 4. Place this under the 7.
8) Subtract 7 and 4 to get 3.
9) Add a 0 and a decimal point. Carry down as before. Dividing to a decimal, you can add as many zeroes as the problem requires.
10) Divide 30 and 4 to get 7.
11) Multiply 4 and 7 to get 28. Place this under the 30.
12) Subtract 30 and 28 to 2.
13) Add another 0 and a decimal point. Carry down as before.
14) Divide 20 by 4 to get 5.
15) Multiply 4 and 5 to get 20. The remainder is 0, therefore you have completed the division problem.

The answer is 31.75!

Step 5: Divide With More Than One Digit

Last method! Dividing when the divisor is more than one digit, like 63.

1) Setup the division problem (2856/84).
2) Divide 285 by 84 to get 3. Place this on top of the 5 and the division sign.
3) Multiply the 3 and 84 to get 252. Place this under the 285.
4) Subtract 285 and 252 to get 33.
5) Carry down the 6.
6) Divide 336 by 84 to get 4. Place this on top of the 6 and the division sign.
7) Multiply 4 and 84 to get 336.
8) Subtract 336 and 336 to get 0.

The answer is 34!

Step 6: Conclusion

Now you know how to divide!

Remember that you can't divide by zero.

RainiG (author)ZeroXL912015-08-31

you're not the only one, im in 9th :)

Nous1935 (author)RainiG2015-09-23

I'm in 10th grade.. I've been making it in school so far. I used to be so good at math.. I'm not sure what happened. I still am, but I just don't know how to divide, multiply large numbers, or add/subtract. I feel almost ashamed of myself.

Give me any geometry or algebra questions and I'll be able to solve them. But I can't do these...

LilzyP (author)2017-06-07

I never learned about step 4!!!!

LilzyP (author)2017-06-07

I am going into 7th grade, but I am still awful at this! Especially the two digit ones.

Thanks Y'all

Wynteir (author)2016-09-20

It didn't help me as much, more of got me confused but, if you got through this without getting confused, good for you! I couldn't do what you did :/

Illuminati Denied (author)2016-09-16

I can't divide anything not decimal fraction not even basic math

adriana_66_55 (author)2016-01-03

I am in 6th grade and I don't know how to divided my teacher Is mean and she call me up in front of the class and I look stupid I come home crying I ask my sister for help but she says I am dumb I need help I hate going up in front of the class looking dumb

natsucks (author)adriana_66_55 2016-01-28

I'm 18 and just learning multiplication and division! I left school because I never ever got the hang of it and here I am being 18 years old learning 6th grade math! once you get the hang of it it'll be really easy for you. you're not dumb you're learning and that's ok! I still hate going in front of the classroom because I'm afraid of making mistakes. But we're human and it's good to make mistakes so you can learn from them! don't cry about it instead just teach yourself! practice makes perfect! I hope everything goes good for you!! you're gonna do great I believe in you :)

Mylifetoo (author)adriana_66_55 2016-01-25

me too my teacher is also mean I know what your feeling and everything is going to be alright

blairz (author)2015-10-16

CharleneR6 (author)blairz2015-10-27

Don't feel bad, I'm 30 and have to relearn this crap. I chose to party and skip school instead of learning so now I'm a 30 year old ignorant idiot. Please don't be like me, go to school and pay attention. You have the rest of your life to screw up after school.

poke_mann (author)2015-12-01

And this is why we have calculators . . .

FouadA4 (author)2015-11-07

I'm a 31 year old mechanical engineer with 3 years of work experience and a part time graduate student studying thermal and fluid dynamic systems modeling....and just now learned about step 4. Never knew you could get actual decimals from this method of division rather than just remainders.

TheAnimeCow (author)2015-10-19

I forgot how to divide and I have always sucked at long division...........

so it kinda took me a while to get this down I have always succeeded past school expectations so i need this to remember how again so thank you for this

lyzux (author)2015-10-15

High school graduate of 2 years and forgot how to divide.. Thank you so much for the reminder

Lovekiss12345 (author)AmberW82015-08-31

Do you know how the divid decimals

Are you going to help or not so I can get some one

Zaberk (author)2015-05-28

Thanks, even though I'm still in 7th I never knew how to divide. I was good at evrything else but division just was too hard for me to explain and I was embarrassed to ask my teacher because everyone already knows how to. Since I couldn't i searched this up and some comments helped so yeah, I guess it makes some things easier, but not when your in advance math and have to do algebra and geometry

dkraja (author)2015-03-13
