1. Division

2. Just as multiplication can be expressed as a series of additions, division can be seen as a series of subtractions. 21 ÷ 7 asks how many times 7 can be subtracted from 21.

3. Division In Binary, subtraction is done by adding a negative value… So division is the repeated addition of a negative value.
