0.17

Explanation:

0.85 can be written as 85/100. That's where the decimal point comes from.
The number of zeroes is the same as the number of digits after the decimal, if the zeroes are in the denominator.

So, 0.85div5 can be written as 85/100xx1/5 = cancel(85)^17/100xx1/cancel(5)_1 = (17xx1)/(100xx1) = 17/100 = 0.17
