If we divide 8686 by 991, we get 8 and a remainder of 758.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 7928 from 8686 and we're left with 758.
Bring next digit (9) of the dividend behind the 758 and repeat the process: 7589 / 991

Advancing to step 6:
7589 divided by 991 is 7 with a remainder of 652.
Use 7 as the next digit of our solution. 
Result so far: 287.0
The remainder is 652 after subtracting 6937 from 7589.
Fetch the next digit (0) from the dividend, attach it to 652 and continue: 6520 / 991

Let's proceed to step 7:
6520 divided by 991 is 6 with a remainder of 574.
Put 6 as the next digit of the answer. 
Result so far: 2876.0
Subtract 5946 from 6520 to get 574.
Bring next digit (1) of the dividend behind the 574 and repeat the process: 5741 / 991

Step 8:
5741 divided by 991 is 5 with a remainder of 786.
Write down 5 as next digit of the result. 
Result so far: 28765.0
The remainder is 786 after subtracting 4955 from 5741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Advancing to step 9:
991 goes into 7860 7 times with a remainder of 923.
Record the quotient 7 as the next digit in the result. 
Result so far: 28765.7
Subtracting 6937 from 7860 leaves us with 923.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9230, and continue the process.

Advancing to step 10:
991 goes into 9230 9 times with a remainder of 311.
Write down 9 as next digit of the result. 
Result so far: 28765.79
Subtract 8919 from 9230 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 11:
991 goes into 3110 3 times with a remainder of 137.
The next digit of our result is 3. 
Result so far: 28765.793
If we subtract 2973 from 3110, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Let's proceed to step 12:
If we divide 1370 by 991, we get 1 and a remainder of 379.
Use 1 as the next digit of our solution. 
Result so far: 28765.7931
If we subtract 991 from 1370, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 13:
If we divide 3790 by 991, we get 3 and a remainder of 817.
Record the quotient 3 as the next digit in the result. 
Result so far: 28765.79313
Deduct 2973 from 3790 and we're left with 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

Advancing to step 14:
The number 991 fits into 8170 8 times, leaving a remainder of 242.
Write down 8 as next digit of the result. 
Result so far: 28765.793138
Subtracting 7928 from 8170 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 15:
991 goes into 2420 2 times with a remainder of 438.
Write down 2 as next digit of the result. 
Result so far: 28765.7931382
Subtract 1982 from 2420 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 16:
When dividing 4380 by 991, we get 4 with a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 28765.79313824
Subtracting 3964 from 4380 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

The final result is 28765.79313824 with a remainder of 4.16e-07.
