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!
