Divide Decimals By Decimals
Concept
Dividing with decimals works exactly like regular long division, with just one difference. When the dividend is a decimal number, put a decimal point right above the decimal in the answer section too.
Rules
When dividing a multi-digit dividend by a 1 or 2-digit divisor:
1. Place the divisor to the left of the dividend.
2. First, divide the first 2 digits of the dividend by the divisor. To do this, find a multiple of the divisor that is close to, by not greater than, the number.
3. Subtract the multiple from the 2-digit number and write the difference below it.
4. Bring down the third digit of the dividend and place it next to the difference, making a new 2-digit number.
5. Divide this new 2-digit number by the divisor. To do this, find a multiple of the divisor that is close to, by not greater than, the number.
6. The difference may be 0, or there may be a remainder.

Dividend – The number being divided.

Quotient – The answer to a division problem. In this case, a whole number.
Remainder – Sometimes a division problem doesn’t work out to a whole number. A number that is remaining is called the remainder.
