If we subtract 6930 from 7400, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 12:
The number 990 fits into 4700 4 times, leaving a remainder of 740.
Write down 4 as next digit of the result. 
Result so far: 27585.6474
If we take 3960 away from 4700, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 13:
If we divide 7400 by 990, we get 7 and a remainder of 470.
Use 7 as the next digit of our solution. 
Result so far: 27585.64747
Subtract 6930 from 7400 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 14:
990 goes into 4700 4 times with a remainder of 740.
Write down 4 as next digit of the result. 
Result so far: 27585.647474
Subtracting 3960 from 4700 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.
