What is 8.7 divided by 53.07 step by step?
tresset_1 [31]

Shift the decimal points of both 8.7 and 53.07 to the right by 2 decimal places.

(This is needed to convert 53.07 to 5307, since long division must divide by a whole number.)

Set up the long division.

5307|870

Therefore your answer should be 0.1639.
