\lim_{b \to 0^+} {a \over b} = +\infty

and 

$$\lim\limits_{b\to^-0}\frac{a}{b}=-\infty$$

Note for both this situations a is not equal to zero.

so if you approach 0 from above the answer tends to +infinty

and if you approach 0 from below the answer tends to -infinity

Which is a part of the logic explaining why anything divided by 0 is undefined.

Melody elaborates on it, and her graph makes it easier to understand.
