Let's divide 13231391 by 633
We want to figure out the number of times 13231391 can be divided by 633.

Advancing to step 1:
The number 633 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 633

On to step 2:
13 divided by 633 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 633

Going ahead to step 3:
The number 633 fits into 132 0 times, leaving a remainder of 132.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 132 after subtracting 0 from 132.
Fetch the next digit (3) from the dividend, attach it to 132 and continue: 1323 / 633

Advancing to step 4:
633 can be fit into 1323 2 times, resulting in a remainder of 57.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1266 from 1323 to get 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 633

Advancing to step 5:
571 divided by 633 is 0 with a remainder of 571.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 571 and we're left with 571.
Include the next digit (3) from the dividend after 571, then repeat: 5713 / 633

Moving on to step 6:
If we divide 5713 by 633, we get 9 and a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
If we subtract 5697 from 5713, we get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 633

Going ahead to step 7:
When dividing 169 by 633, we get 0 with a remainder of 169.
Use 0 as the next digit of our solution. 
Result so far: 2090.0
Deduct 0 from 169 and we're left with 169.
Include the next digit (1) from the dividend after 169, then repeat: 1691 / 633

On to step 8:
1691 divided by 633 is 2 with a remainder of 425.
The number 2 becomes the next digit in our result. 
Result so far: 20902.0
Deduct 1266 from 1691 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 9:
The number 633 fits into 4250 6 times, leaving a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 20902.6
Subtracting 3798 from 4250 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 10:
When dividing 4520 by 633, we get 7 with a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 20902.67
If we take 4431 away from 4520, we end up 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.

Let's proceed to step 11:
633 goes into 890 1 times with a remainder of 257.
Write down 1 as next digit of the result. 
Result so far: 20902.671
If we take 633 away from 890, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 12:
633 can be fit into 2570 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 20902.6714
If we take 2532 away from 2570, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
633 can be fit into 380 0 times, resulting in a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 20902.6714
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 14:
633 goes into 3800 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 20902.671406
Subtracting 3798 from 3800 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 15:
633 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 20902.671406
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
If we divide 200 by 633, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 20902.671406
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 20902.671406 with a balance of 2e-07.
