Dividing is a skill of life. Ever since you learned it from school, you have been using it up to now.
But some people were never taught how to divide. This Instructable will teach you how to divide like how most people learned it in grade school, using "long division."

First of all, there are three different "methods" that I will being teaching to you. To learn all the methods you will need a pencil and lots of paper. You may also want a calculator to double-check your answer.

I'm in 8th grade and i forgot how too divide once i got in a car accident . .
Well this has really helped me lots
"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!
Hey thanks a lot!! You really helped me out!!
4 goes into 3 no times, so carry down a zero. 4 goes into 30 7 times, 7*4 is 28 so 2 left over, carry a zero down and 4 goes into 20 exactly 5 times with no remainder, hence .75.
Try dividing 10 by 7 and continue the process down until you see a pattern emerging.
but i went to Google and type "how to divide" and i click your website.
it helped me... t.y
i will be visiting your website when i need help and when i have free time to teach my self...t.y so much .
