Well... I'm not too great at calculations in my head, but here's one way.

The question is... how many times does  0.04  go into  3.2  ?

 4 goes into 32 8 times, so... 0.4 goes into 32 80 times, 0.04 goes into 32 800 times, and 0.04 goes into 3.2 80 times.

Here's a suggestion if the fractions combined with decimals are messing with your mind.

$$\frac{3.2}{0.04}*\frac{100}{100}=\frac{320}{4}$$

Multiplying by 100/100 has no effect on the value of this fraction as it is equivalent of multiplying by 1.

$$\frac{320}{4}=\frac{32*10}{4}=\frac{8*10}{1}=80$$
