Deduct 4722 from 5000 and we're left with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Moving on to step 11:
The number 787 fits into 2780 3 times, leaving a remainder of 419.
Use 3 as the next digit of our solution. 
Result so far: 103580.063
The remainder is 419 after subtracting 2361 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 12:
When dividing 4190 by 787, we get 5 with a remainder of 255.
The next digit of our result is 5. 
Result so far: 103580.0635
Deduct 3935 from 4190 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 13:
787 can be fit into 2550 3 times, resulting in a remainder of 189.
Record the quotient 3 as the next digit in the result. 
Result so far: 103580.06353
If we subtract 2361 from 2550, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 14:
787 goes into 1890 2 times with a remainder of 316.
Use 2 as the next digit of our solution. 
Result so far: 103580.063532
Subtract 1574 from 1890 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 15:
The number 787 fits into 3160 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 103580.0635324
If we subtract 3148 from 3160, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
787 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 103580.0635324
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.
