Dividing a Decimal by a Decimal
• Move the decimal point in the divisor to the right, until it becomes a WHOLE number.
• Move the decimal point in the dividend the same number of places to the right that you moved the decimal point in the divisor.
(Remember… what you do to one side, you must do to the other)

Example 30.38 13.3
The decimal must be moved 2 spaces to the right.
When we move this one 2 spaces, we find that we need to add a space. What will we fill it with?
Answer: Fill it in with a 0. 13.3 becomes 1330
SO, our problem becomes 038 into 1330. 038 is the same as 38.
