Going ahead to step 9:
4680 divided by 873 is 5 with a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 35607.5
Subtracting 4365 from 4680 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 10:
When dividing 3150 by 873, we get 3 with a remainder of 531.
Use 3 as the next digit of our solution. 
Result so far: 35607.53
If we take 2619 away from 3150, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 11:
The number 873 fits into 5310 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 35607.536
The remainder is 72 after subtracting 5238 from 5310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
873 can be fit into 720 0 times, resulting in a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 35607.536
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Moving on to step 13:
873 can be fit into 7200 8 times, resulting in a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 35607.53608
If we subtract 6984 from 7200, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 14:
When dividing 2160 by 873, we get 2 with a remainder of 414.
Put 2 as the next digit of the answer. 
Result so far: 35607.536082
If we take 1746 away from 2160, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 15:
873 goes into 4140 4 times with a remainder of 648.
The next digit of our result is 4. 
Result so far: 35607.5360824
If we take 3492 away from 4140, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Moving on to step 16:
When dividing 6480 by 873, we get 7 with a remainder of 369.
Put 7 as the next digit of the answer. 
Result so far: 35607.53608247
The remainder is 369 after subtracting 6111 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.
