Question

Assume N is my favorite number 7....

7 divided by 0 -> 7 / 0 -> 0


Now you use your favorite number and see what you get.

Division by zero is by means not possible.

n/0 = 0 would result into n = 0*0 = 0^2. If you set n = 0: 0 = 0^2 sqrt(0) = 0. But 0/0 = (0^1)/(0^1) = 0^(1-1) = 0^0 = 1 != 0.
Same for all other integers. 5/0 = 0 5 != 0^2.
