Put 2 as the next digit of the answer. 
Result so far: 39.467532
Subtract 154 from 190 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 11:
If we divide 360 by 77, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 39.4675324
If we take 308 away from 360, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
