We divide 91037636 by 991
We want to figure out the number of times 91037636 can be divided by 991.

Step 1:
If we divide 9 by 991, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 991

On to step 2:
If we divide 91 by 991, we get 0 and a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 991

Advancing to step 3:
910 divided by 991 is 0 with a remainder of 910.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 910 leaves us with 910.
Append the next digit (3) from the dividend to 910 and continue with: 9103 / 991

Step 4:
If we divide 9103 by 991, we get 9 and a remainder of 184.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 184 after subtracting 8919 from 9103.
Include the next digit (7) from the dividend after 184, then repeat: 1847 / 991

Going ahead to step 5:
When dividing 1847 by 991, we get 1 with a remainder of 856.
Write down 1 as next digit of the result. 
Result so far: 91.0
The remainder is 856 after subtracting 991 from 1847.
Append the next digit (6) from the dividend to 856 and continue with: 8566 / 991

On to step 6:
8566 divided by 991 is 8 with a remainder of 638.
The number 8 becomes the next digit in our result. 
Result so far: 918.0
Deduct 7928 from 8566 and we're left with 638.
Include the next digit (3) from the dividend after 638, then repeat: 6383 / 991

Going ahead to step 7:
991 can be fit into 6383 6 times, resulting in a remainder of 437.
Put 6 as the next digit of the answer. 
Result so far: 9186.0
Subtracting 5946 from 6383 leaves us with 437.
Fetch the next digit (6) from the dividend, attach it to 437 and continue: 4376 / 991

Advancing to step 8:
991 can be fit into 4376 4 times, resulting in a remainder of 412.
The next digit of our result is 4. 
Result so far: 91864.0
Subtract 3964 from 4376 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 9:
991 can be fit into 4120 4 times, resulting in a remainder of 156.
The next digit of our result is 4. 
Result so far: 91864.4
Deduct 3964 from 4120 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 10:
The number 991 fits into 1560 1 times, leaving a remainder of 569.
The next digit of our result is 1. 
Result so far: 91864.41
Subtract 991 from 1560 to get 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Let's proceed to step 11:
When dividing 5690 by 991, we get 5 with a remainder of 735.
Write down 5 as next digit of the result. 
Result so far: 91864.415
If we take 4955 away from 5690, we end up with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Let's proceed to step 12:
7350 divided by 991 is 7 with a remainder of 413.
Record the quotient 7 as the next digit in the result. 
Result so far: 91864.4157
If we take 6937 away from 7350, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

On to step 13:
The number 991 fits into 4130 4 times, leaving a remainder of 166.
Write down 4 as next digit of the result. 
Result so far: 91864.41574
Subtracting 3964 from 4130 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 14:
If we divide 1660 by 991, we get 1 and a remainder of 669.
Record the quotient 1 as the next digit in the result. 
Result so far: 91864.415741
The remainder is 669 after subtracting 991 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Advancing to step 15:
991 goes into 6690 6 times with a remainder of 744.
The next digit of our result is 6. 
Result so far: 91864.4157416
Subtracting 5946 from 6690 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Advancing to step 16:
The number 991 fits into 7440 7 times, leaving a remainder of 503.
Write down 7 as next digit of the result. 
Result so far: 91864.41574167
The remainder is 503 after subtracting 6937 from 7440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

The final outcome is 91864.41574167, with a leftover of 5.03e-07.
