0/0 is undefined because everything would be a valid result. 0/0 is basically finding solutions for 0*x=0 and everything you put into x would satisfy the equation.

This doesn't clearly identify a problem IMO. Division by a number is defined as multiplication by the multiplicative inverse, and 0 has no multiplicative inverse because 0x = 1 has no solutions.
