If we subtract 6128 from 6299, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Going ahead to step 9:
766 can be fit into 1710 2 times, resulting in a remainder of 178.
The next digit of our result is 2. 
Result so far: 27388.2
Subtracting 1532 from 1710 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.

Step 10:
766 goes into 1780 2 times with a remainder of 248.
The next digit of our result is 2. 
Result so far: 27388.22
If we take 1532 away from 1780, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 27388.22 with a remaining 0.248.
