It doesn't equal infinity, it is undefined. x/n approaches infinity as n goes to 0, but at n=0 there is no answer. One way to think of it is x/n = m therefore n * m = x. You can recover the original value by multiplying the result by the denominator. But when n=0, you can't multiply 0 by anything to get x. There is just no such number.
