To divide a decimal by a whole number, divide as you would for whole
numbers; and place a decimal point in the answer so that it lines up with
the decimal point in the dividend.
If after dividing you have a remainder, add a zero to the dividend and
continue to divide until there is no remainder or the decimals recur (i.e.
repeat).

Solution:
Alternatively, we can set out the solution as follows:

Alternatively, we can set out the solution as follows:
Example 29
Solution:
Alternatively, we can set out the solution as follows:
Note:
- We added a trailing zero to 7.4 when 4 would not divide into 2.
- Adding a trailing zero (or zeros) to a decimal number does not alter
its value.
