# Division technique

The technique to carry out two's complement division is to convert the numbers to positive, complete the division following the method outlined in the lesson [Division in Binary](https://www.educative.io/courses/number-systems-for-computer-scientists/division-in-binary), and then adjust the sign.

The notation is:
>$A$ $\overline{)B} =C$ , where $A$ is the *divisor*, $B$ is the *dividend* and $C$ is the quotient.

The sign of the quotient will only be negative if the signs of the dividend and the divisor differ, and the sign of the remainder will be the same as the dividend.
