Suppose we want to divide 52 by 0.1
This is the same as asking "How many 0.1s (tenths) are there in 52?"
There are 10 tenths in 1, and so there are 52 × 10 tenths in 52.
So 52 ÷ 0.1 = 520
Similarly, 39 ÷ 0.01 means "How many 0.01s (hundredths) are there in 39?"
There are 100 hundredths in 1, and so there are 39 × 100 hundredths in 39.
So 39 ÷ 0.01 = 3900
