509 goes into 570 1 times with a remainder of 61.
The next digit of our result is 1. 
Result so far: 27104.1
Subtracting 509 from 570 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 10:
509 goes into 610 1 times with a remainder of 101.
The next digit of our result is 1.
