Why is it impossible. I really need to know this now. I want to try to divide by 0 and am afraid of doing so, because everyone tells me it is impossible.

Theoretically, Zero is infinitely far back from any number, the Quotient will be equally infinitely far forward. This is because if you Divide something by Zero, following the principle that the smaller the Divisor, the larger the Quotient, and how Zero is infinitely small, the Quotient will be infinitely large... Or Infinity.
