How do you divide decimals by whole numbers?

Step 1: Set up your division problem.
Step 2: Place a decimal above the division bracket (directly above the one in the dividend).
Step 3: Divide like normal.

Example: Divide 0.69 by 3

What is the process for dividing decimals by decimals?

Step 1: Set up your division problem.
Step 2: Move the decimal (in the divisor) to the right until you have a whole number.
Step 3: Move the decimal (in the dividend) to the right the same amount of spaces as in Step 2.
Step 4: Place a decimal above the division bracket, directly above the (new) one in the dividend.
Step 5: Divide like normal.

Example: Divide 23.1 by 7.2

What are some common mistakes to avoid when dividing decimals?

1. Not turning the divisor into a whole number.
2. Once turning the divisor into a whole number, not also moving the decimal of the dividend. (Or not moving it the correct number of spaces.)
3. Not placing a decimal in the quotient (solution) prior to dividing.
4. Not adding extra zeroes in the dividend to fill empty place values when moving the decimal over.
5. Not adding extra zeroes in the dividend after the decimal to complete the division.
