Let's divide 21816532 by 831
We're looking to find how many times 831 goes into 21816532.

Advancing to step 1:
The number 831 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 831

Let's proceed to step 2:
831 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 831

Let's proceed to step 3:
If we divide 218 by 831, we get 0 and a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Fetch the next digit (1) from the dividend, attach it to 218 and continue: 2181 / 831

Advancing to step 4:
The number 831 fits into 2181 2 times, leaving a remainder of 519.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1662 from 2181 leaves us with 519.
Fetch the next digit (6) from the dividend, attach it to 519 and continue: 5196 / 831

On to step 5:
The number 831 fits into 5196 6 times, leaving a remainder of 210.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 4986 away from 5196, we end up with 210.
Take the next digit (5) from the dividend and append it to 210, then repeat: 2105 / 831

Going ahead to step 6:
831 can be fit into 2105 2 times, resulting in a remainder of 443.
Use 2 as the next digit of our solution. 
Result so far: 262.0
The remainder is 443 after subtracting 1662 from 2105.
Include the next digit (3) from the dividend after 443, then repeat: 4433 / 831

On to step 7:
If we divide 4433 by 831, we get 5 and a remainder of 278.
The next digit of our result is 5. 
Result so far: 2625.0
The remainder is 278 after subtracting 4155 from 4433.
Grab the next digit (2) from the dividend, add it to 278, then carry on: 2782 / 831

Step 8:
When dividing 2782 by 831, we get 3 with a remainder of 289.
The number 3 becomes the next digit in our result. 
Result so far: 26253.0
Subtracting 2493 from 2782 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 9:
When dividing 2890 by 831, we get 3 with a remainder of 397.
Use 3 as the next digit of our solution. 
Result so far: 26253.3
Deduct 2493 from 2890 and we're left with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 10:
831 goes into 3970 4 times with a remainder of 646.
Record the quotient 4 as the next digit in the result. 
Result so far: 26253.34
Deduct 3324 from 3970 and we're left with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Advancing to step 11:
If we divide 6460 by 831, we get 7 and a remainder of 643.
Use 7 as the next digit of our solution. 
Result so far: 26253.347
Subtracting 5817 from 6460 leaves us with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Let's proceed to step 12:
If we divide 6430 by 831, we get 7 and a remainder of 613.
Write down 7 as next digit of the result. 
Result so far: 26253.3477
Subtract 5817 from 6430 to get 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

The quotient of the division is 26253.3477, and the remainder is 0.00613.
