Put 8 as the next digit of the answer. 
Result so far: 74751.8
Subtracting 5904 from 6280 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 10:
If we divide 3760 by 738, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 74751.85
The remainder is 70 after subtracting 3690 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
700 divided by 738 is 0 with a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 74751.85
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 12:
The number 738 fits into 7000 9 times, leaving a remainder of 358.
The next digit of our result is 9. 
Result so far: 74751.8509
Subtract 6642 from 7000 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Going ahead to step 13:
If we divide 3580 by 738, we get 4 and a remainder of 628.
The number 4 becomes the next digit in our result. 
Result so far: 74751.85094
Subtracting 2952 from 3580 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 14:
6280 divided by 738 is 8 with a remainder of 376.
The next digit of our result is 8. 
Result so far: 74751.850948
Subtract 5904 from 6280 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 15:
738 goes into 3760 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 74751.8509485
If we subtract 3690 from 3760, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
738 can be fit into 700 0 times, resulting in a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 74751.8509485
Subtract 0 from 700 to get 700.
