Steps for decimal division:
1. Move the decimal point in the divisor to the right until the divisor is a whole number.
2. Move the decimal point in the dividend to the right the same number of places as in Step 1.
3. Divide until the remainder is 0.
The decimal point in the answer lines up with the decimal point in the dividend.
 divisor → 5.44 32.368 ↑ dividend

Example 1:

 3.7 11.84

Adjust the decimal points in the divisor and the dividend.

Now divide.
 ``` 3 37)118.4 -111 7 ``` ``` 3.2 ← Place the decimal point in the 37)118.4 answer so that it lines up with -111 the decimal point in the dividend. 7 4 -7 4 0 ```
 3.7 11.84

Example 2: Adding zero

 4.5 21.6

Adjust the decimal points in the divisor and the dividend.

Now divide.
 ``` 4 45)216 -180 36 ``` ``` 4 45)216.0 -180 ↓ 36 0 Since there is a remainder, a zero is brought down. ``` ``` 4.8 ← Place the decimal point in the 45)216.0 answer so that it lines up with -180 the decimal point in the dividend. 36 0 -36 0 0 ```
 4.5 21.6
