A 4-bit integer division circuit is given below. You are asked to divide the least significant digit (rightmost) of your student number by the tens (second rightmost) digit of your student number in 4 bits binary numbers using the division circuit below. For example, if your student number is 1030510394 you will divide 4 (0100 in 4-bits binary) by 9 (1001 in 4-bits binary).

4 /9 = ?
