Our goal is to divide 8353660 by 991.

Advancing to step 1:
The number 991 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 991

Going ahead to step 2:
When dividing 83 by 991, we get 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 991

Let's proceed to step 3:
991 can be fit into 835 0 times, resulting in a remainder of 835.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 835 to get 835.
Bring next digit (3) of the dividend behind the 835 and repeat the process: 8353 / 991

Step 4:
If we divide 8353 by 991, we get 8 and a remainder of 425.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7928 away from 8353, we end up with 425.
Take the next digit (6) from the dividend and append it to 425, then repeat: 4256 / 991

Moving on to step 5:
When dividing 4256 by 991, we get 4 with a remainder of 292.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtracting 3964 from 4256 leaves us with 292.
Take the next digit (6) from the dividend and append it to 292, then repeat: 2926 / 991

Going ahead to step 6:
991 can be fit into 2926 2 times, resulting in a remainder of 944.
Put 2 as the next digit of the answer. 
Result so far: 842.0
The remainder is 944 after subtracting 1982 from 2926.
Fetch the next digit (0) from the dividend, attach it to 944 and continue: 9440 / 991

Moving on to step 7:
991 goes into 9440 9 times with a remainder of 521.
The next digit of our result is 9. 
Result so far: 8429.0
The remainder is 521 after subtracting 8919 from 9440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Advancing to step 8:
991 goes into 5210 5 times with a remainder of 255.
The next digit of our result is 5. 
Result so far: 8429.5
Deduct 4955 from 5210 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.

Let's proceed to step 9:
The number 991 fits into 2550 2 times, leaving a remainder of 568.
Write down 2 as next digit of the result. 
Result so far: 8429.52
Subtract 1982 from 2550 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 10:
991 goes into 5680 5 times with a remainder of 725.
Put 5 as the next digit of the answer. 
Result so far: 8429.525
The remainder is 725 after subtracting 4955 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Let's proceed to step 11:
If we divide 7250 by 991, we get 7 and a remainder of 313.
Put 7 as the next digit of the answer. 
Result so far: 8429.5257
Subtract 6937 from 7250 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 12:
The number 991 fits into 3130 3 times, leaving a remainder of 157.
The number 3 becomes the next digit in our result. 
Result so far: 8429.52573
The remainder is 157 after subtracting 2973 from 3130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 13:
The number 991 fits into 1570 1 times, leaving a remainder of 579.
Use 1 as the next digit of our solution. 
Result so far: 8429.525731
Deduct 991 from 1570 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Advancing to step 14:
When dividing 5790 by 991, we get 5 with a remainder of 835.
The next digit of our result is 5. 
Result so far: 8429.5257315
Deduct 4955 from 5790 and we're left with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Step 15:
991 goes into 8350 8 times with a remainder of 422.
Put 8 as the next digit of the answer. 
Result so far: 8429.52573158
Subtracting 7928 from 8350 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

In conclusion, the division gives 8429.52573158 with a balance of 4.22e-07.
