We're dividing 39201523 by 991 
We want to divide 39201523 by 991.

On to step 1:
The number 991 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 991

Advancing to step 2:
If we divide 39 by 991, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 991

Going ahead to step 3:
392 divided by 991 is 0 with a remainder of 392.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 392, we get 392.
Fetch the next digit (0) from the dividend, attach it to 392 and continue: 3920 / 991

Going ahead to step 4:
The number 991 fits into 3920 3 times, leaving a remainder of 947.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2973 from 3920 to get 947.
Include the next digit (1) from the dividend after 947, then repeat: 9471 / 991

Step 5:
If we divide 9471 by 991, we get 9 and a remainder of 552.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 8919 from 9471 to get 552.
Take the next digit (5) from the dividend and append it to 552, then repeat: 5525 / 991

Let's proceed to step 6:
The number 991 fits into 5525 5 times, leaving a remainder of 570.
Write down 5 as next digit of the result. 
Result so far: 395.0
If we subtract 4955 from 5525, we get 570.
Take the next digit (2) from the dividend and append it to 570, then repeat: 5702 / 991

Step 7:
When dividing 5702 by 991, we get 5 with a remainder of 747.
Write down 5 as next digit of the result. 
Result so far: 3955.0
If we take 4955 away from 5702, we end up with 747.
Include the next digit (3) from the dividend after 747, then repeat: 7473 / 991

Advancing to step 8:
If we divide 7473 by 991, we get 7 and a remainder of 536.
The next digit of our result is 7. 
Result so far: 39557.0
If we subtract 6937 from 7473, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 9:
The number 991 fits into 5360 5 times, leaving a remainder of 405.
The next digit of our result is 5. 
Result so far: 39557.5
Subtract 4955 from 5360 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 10:
4050 divided by 991 is 4 with a remainder of 86.
The next digit of our result is 4. 
Result so far: 39557.54
If we subtract 3964 from 4050, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 11:
If we divide 860 by 991, we get 0 and a remainder of 860.
Record the quotient 0 as the next digit in the result. 
Result so far: 39557.54
If we subtract 0 from 860, we get 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

Moving on to step 12:
991 can be fit into 8600 8 times, resulting in a remainder of 672.
Put 8 as the next digit of the answer. 
Result so far: 39557.5408
Subtracting 7928 from 8600 leaves us with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 13:
6720 divided by 991 is 6 with a remainder of 774.
Record the quotient 6 as the next digit in the result. 
Result so far: 39557.54086
The remainder is 774 after subtracting 5946 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Step 14:
991 goes into 7740 7 times with a remainder of 803.
Put 7 as the next digit of the answer. 
Result so far: 39557.540867
Deduct 6937 from 7740 and we're left with 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

Let's proceed to step 15:
991 can be fit into 8030 8 times, resulting in a remainder of 102.
Record the quotient 8 as the next digit in the result. 
Result so far: 39557.5408678
Subtracting 7928 from 8030 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 16:
When dividing 1020 by 991, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 39557.54086781
If we subtract 991 from 1020, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Our division results in 39557.54086781 with a remaining 2.9e-08.
