We divide 21027745 by 831
We want to divide 21027745 by 831.

Going ahead to step 1:
If we divide 2 by 831, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 831

On to step 2:
831 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 831

Moving on to step 3:
210 divided by 831 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Include the next digit (2) from the dividend after 210, then repeat: 2102 / 831

Going ahead to step 4:
831 goes into 2102 2 times with a remainder of 440.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1662 from 2102 leaves us with 440.
Fetch the next digit (7) from the dividend, attach it to 440 and continue: 4407 / 831

Moving on to step 5:
When dividing 4407 by 831, we get 5 with a remainder of 252.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 4155 from 4407 and we're left with 252.
Append the next digit (7) from the dividend to 252 and continue with: 2527 / 831

Moving on to step 6:
When dividing 2527 by 831, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 253.0
The remainder is 34 after subtracting 2493 from 2527.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 831

Moving on to step 7:
When dividing 344 by 831, we get 0 with a remainder of 344.
Record the quotient 0 as the next digit in the result. 
Result so far: 2530.0
If we take 0 away from 344, we end up with 344.
Bring next digit (5) of the dividend behind the 344 and repeat the process: 3445 / 831

Let's proceed to step 8:
831 goes into 3445 4 times with a remainder of 121.
Record the quotient 4 as the next digit in the result. 
Result so far: 25304.0
Deduct 3324 from 3445 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 9:
The number 831 fits into 1210 1 times, leaving a remainder of 379.
The number 1 becomes the next digit in our result. 
Result so far: 25304.1
Subtracting 831 from 1210 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 10:
831 can be fit into 3790 4 times, resulting in a remainder of 466.
Put 4 as the next digit of the answer. 
Result so far: 25304.14
If we take 3324 away from 3790, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 11:
831 goes into 4660 5 times with a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 25304.145
If we subtract 4155 from 4660, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Advancing to step 12:
831 goes into 5050 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 25304.1456
The remainder is 64 after subtracting 4986 from 5050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
831 goes into 640 0 times with a remainder of 640.
The number 0 becomes the next digit in our result. 
Result so far: 25304.1456
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 14:
6400 divided by 831 is 7 with a remainder of 583.
Record the quotient 7 as the next digit in the result. 
Result so far: 25304.145607
If we subtract 5817 from 6400, we get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Advancing to step 15:
If we divide 5830 by 831, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 25304.1456077
Deduct 5817 from 5830 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 25304.1456077 with a balance of 1.3e-07.
