Except it doesn't necessarily go towards (positive) infinity. Use a negative dividend, and you approach negative infinity instead. The same is obviously true if you use a negative divisor instead, and you get positive infinity again if both are negative. So division by zero is impossible because you can't meaningfully define it (in the general case).
