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!

I'm looking for how to make the remainder into a decimal =/

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

lol in my problem the number outside the square thingy is larger than the number in the square thingy... 7 wouldn't fit into 8!

Also I think you forgot to say (Or did I read over this?) what to do if the divisor is bigger than the first number of the dividend. Eg. 27 Divided by 9.

With all due respect to the author, I think he/she has overlooked the fact that if you do not know how to divide, then even the answer of "1" in the simple step of
"8 divided by 7 = 1" is NOT self-explanatory. (Step 2, #4) That could be why people are googling "how to divide" in the first place, because the concept escapes them.

To simplify the expression of plain division into "layman's logic" (this assumes you know how to add, subtract, and multiply):
- For 8 divided by 7, place 8 inside the box, 7 outside
-Ask yourself: How many 7's can fit in an 8?
-OR ask: What number multiplied by 7 gets me the closest to 8, or equal to 8?
-The answer to both questions is 1. Then you can move on to the next steps :)

Now that we have that out, there is an alternative way to deal with the decimal example in Step 4 (Dividing with Decimals): (Hopefully this provide more clarity on how to arrive at the ".75")


1) Given the author's example in Step 4 (127 divided by 4),

2) Do as told, UNTIL you get to Step 8 where it states "Subtract 7 and 4 to get 3"

3) Now, instead of Step 9 where you create "3.0", just drop down a 0 so "3" becomes "30". Indicate this by adding the decimal after 31 just like in the original tutorial such that your quotient (the number on top of the bar) reads "31."

4) Continue long division, by asking yourself:
-I have 4 outside the box
-I have 30 inside the box
-What number multiplied by 4 equals a number that is closest to 30, or equal to 30? (Trial and error, or memorization) The answer is 7

5) 4 x 7 = 28. Place "7" after "31." so the quotient now reads "31.7"

6) 7 x 4 = 28, which I place under 30

7) 30 minus 28 = 2

8) 2 is less than 4 (your divisor), so again, drop a 0 (no need to add another decimal to indicate this after you've done it the first time)

9) Now you have 4 outside the box, and 20 inside

10) What number multiplied by 4 is closest to 20, or equal to 20?

11) 5, because 4 x 5 = 20!

12) You add "5" after "31.7" and have the answer: "31.75" :)

I've attached a sketch (only the last 3 or 4 steps are different) from the tutorial

Hope this helps!
