5.09 x 10-8 / 0.04 x 10-8

Firstly I assume that you mean - people really must learn to use brackets!  (not aimed just at you)

(5.09 x 10-8) / (0.04 x 10-8

the 10-8 s cancel out leaving

5.09/0.04=

$${\frac{{\mathtt{5.09}}}{{\mathtt{0.04}}}} = {\frac{{\mathtt{509}}}{{\mathtt{4}}}} = {\mathtt{127.25}}$$
