you aren't thinking big enough, because it is zero. Calculus was created for the purpose of solving problems which couldn't be solved with algebra,

Calculus is used to solve problems with "infinitely small numbers". The answer to x / ∞ is infinitely small, but not equal to 0. There's a reason for it being called "infinitely small" or "infinitesimal", instead of "0".
