Steps for Division
Dividing with decimals and remainders
- Estimate the divisor, or the second number in the division problem
- Estimate the second number to a number that can be divided by your divisor estimate, but still close to your original number.
- Divide your estimates to get an answer
- Draw a division house
- Put the first number in the problem inside your division house, and put the other number, or divisor next to the house
- If you have a decimal, put it right above itself on top of your house
- Multiply your estimate times the number outside your box
- You should get either a two or three digit number, possibly four
- If that number is bigger than the digits inside the house, multiply it by one less number
- Subtract that answer to the number inside the house by lining the numbers up, so if your answer was a two-digit number, you should be subtracting 2 two-digit numbers. If that answer is bigger than the divisor, don't put it on top of the house. If it is good, keep that answer there.
- Bring down the number next to the numbers in the house you subtracted
- Figure out how many times the number outside the box goes into the number down below
- Subtract your answer from step #11, and get an answer
- If your answer is bigger than your number outside the box, use a lower number. If it isn't put the number you multiplied by on top of the house. The number should be directly above the number that was in the house you subtracted from.
- Repeat steps 9-12 until you have no more numbers left in the house to use
- If you have some numbers left over, put the number next to your answer on top of the house with a "r" next to it like this, r14.
