The next digit of our result is 8. 
Result so far: 67721.8
Subtracting 6472 from 6650 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 10:
809 goes into 1780 2 times with a remainder of 162.
Put 2 as the next digit of the answer.
