It all depends on the divisor.
You need to make sure the decimal of the divisor is at the end.
For example, 2.09 divided by 0.19
You need to move the decimal point of 0.19 two times to the right so the decimal point is at the end.
If the divisor is a whole number, the decimal would stay at the same position.
For example, 25.5 divided by 5, the decimal would stay since 5's decimal point is already at the end (5.)
See attachment if you want to see it visual. Writing on computer is hard tho.
