Okay I'd do this this way: round up to an easier figure: 14000. Divide by 2, and by 2 and by 2 to find 1750.
Now note that the difference from 13852 to 14000 is 148. And 148/8 is 18.5. Therefore the answer is 1750 - 18.5 = 1731.5.
I don't know whether those things are super important to pilots though. That being said, I always find it somewhat amusing when my flight instructor takes a calculator to find out how time an aircraft has left to run on the maintenance sheet.
