We look at the division of 13907706 by 991 
We want to figure out the number of times 13907706 can be divided by 991.

Moving on to step 1:
When dividing 1 by 991, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 991

On to step 2:
The number 991 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 991

Advancing to step 3:
The number 991 fits into 139 0 times, leaving a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 139, we get 139.
Include the next digit (0) from the dividend after 139, then repeat: 1390 / 991

Advancing to step 4:
The number 991 fits into 1390 1 times, leaving a remainder of 399.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 399 after subtracting 991 from 1390.
Fetch the next digit (7) from the dividend, attach it to 399 and continue: 3997 / 991

Let's proceed to step 5:
3997 divided by 991 is 4 with a remainder of 33.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 3964 from 3997 to get 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 991

Step 6:
337 divided by 991 is 0 with a remainder of 337.
Use 0 as the next digit of our solution. 
Result so far: 140.0
Subtract 0 from 337 to get 337.
Include the next digit (0) from the dividend after 337, then repeat: 3370 / 991

Step 7:
If we divide 3370 by 991, we get 3 and a remainder of 397.
Record the quotient 3 as the next digit in the result. 
Result so far: 1403.0
Deduct 2973 from 3370 and we're left with 397.
Take the next digit (6) from the dividend and append it to 397, then repeat: 3976 / 991

Advancing to step 8:
991 goes into 3976 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 14034.0
If we subtract 3964 from 3976, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
991 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 14034.0
Subtracting 0 from 120 leaves us 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:
When dividing 1200 by 991, we get 1 with a remainder of 209.
The next digit of our result is 1. 
Result so far: 14034.01
Deduct 991 from 1200 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 11:
991 goes into 2090 2 times with a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 14034.012
If we subtract 1982 from 2090, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 12:
991 can be fit into 1080 1 times, resulting in a remainder of 89.
The next digit of our result is 1. 
Result so far: 14034.0121
Deduct 991 from 1080 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 13:
890 divided by 991 is 0 with a remainder of 890.
Use 0 as the next digit of our solution. 
Result so far: 14034.0121
If we take 0 away from 890, we end up with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Step 14:
When dividing 8900 by 991, we get 8 with a remainder of 972.
The next digit of our result is 8. 
Result so far: 14034.012108
Subtracting 7928 from 8900 leaves us with 972.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9720, and continue the process.

Going ahead to step 15:
991 can be fit into 9720 9 times, resulting in a remainder of 801.
Write down 9 as next digit of the result. 
Result so far: 14034.0121089
Subtract 8919 from 9720 to get 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

Moving on to step 16:
The number 991 fits into 8010 8 times, leaving a remainder of 82.
The number 8 becomes the next digit in our result. 
Result so far: 14034.01210898
Deduct 7928 from 8010 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

In conclusion, the division gives 14034.01210898 with a balance of 8.2e-08.
