Moving on to step 8:
When dividing 6724 by 839, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 91898.0
Subtracting 6712 from 6724 leaves us with 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 9:
If we divide 120 by 839, we get 0 and a remainder of 120.
The next digit of our result is 0. 
Result so far: 91898.0
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
The number 839 fits into 1200 1 times, leaving a remainder of 361.
Use 1 as the next digit of our solution. 
Result so far: 91898.01
Subtracting 839 from 1200 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

The number 839 fits into 3610 4 times, leaving a remainder of 254.
The next digit of our result is 4. 
Result so far: 91898.014
The remainder is 254 after subtracting 3356 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 12:
The number 839 fits into 2540 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 91898.0143
If we subtract 2517 from 2540, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
230 divided by 839 is 0 with a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 91898.0143
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 14:
The number 839 fits into 2300 2 times, leaving a remainder of 622.
The number 2 becomes the next digit in our result. 
Result so far: 91898.014302
If we subtract 1678 from 2300, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Moving on to step 15:
6220 divided by 839 is 7 with a remainder of 347.
Write down 7 as next digit of the result.
