#### How to Correctly Divide Decimals by Hand

If you can already do long division then you shouldn't have a problem dividing decimals. You just need to remember 2 methods depending upon whether you want to divide by a whole number or decimal.

##### Dividing a Decimal by a Whole Number

If you want to divide a decimal by a whole number e.g. `1.812 / 6` then follow this method:

1. Ignore the decimal points (for now) and do a regular long division.

For example, `1.812 / 6` becomes `1812 / 6`. Let's work it out:

``````  ̲ ̲3̲0̲2
6|1812
``````

2. Put the decimal point back to where it was originally (in the `1812`) and then place one in the answer directly above it, making sure it lines up perfectly.

``````  ̲ ̲.̲3̲0̲2
6|1.812
``````

Now you almost have your answer. Just make sure you always add and/or remove the necessary zeros e.g. `.302` should be `0.302` and if `1.5000` was the answer it should be `1.5` (knocking any zeros off the end).

##### Dividing a Whole Number or Decimal by a Decimal

If you want to divide a whole number or decimal by a decimal e.g. `123 / 4.5` or `1.23 / 4.5` then follow this method:

1. Look at the number you are dividing by e.g. `4.5`.

2. With that decimal, move its point to the right until that decimal becomes a whole number. e.g. `45`

3. Remember how many places to the right the decimal point moved e.g. in this case it was 1.

4. Look at the other number (`123` or `1.23`) and move its decimal point to the right the same number of places you moved the other (1 in this case). For example: `123.0` would become `1230.0` and `1.23` would become `12.3`.

5. Now follow the first method "Dividing a Decimal by a Whole Number" and you'll find your answer.
