We look at the division of 21025265 by 331 
We're looking to find how many times 331 goes into 21025265.

On to step 1:
If we divide 2 by 331, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 331

Going ahead to step 2:
331 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 331

Moving on to step 3:
210 divided by 331 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (2) from the dividend, add it to 210, then carry on: 2102 / 331

Advancing to step 4:
331 goes into 2102 6 times with a remainder of 116.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 116 after subtracting 1986 from 2102.
Grab the next digit (5) from the dividend, add it to 116, then carry on: 1165 / 331

Advancing to step 5:
If we divide 1165 by 331, we get 3 and a remainder of 172.
The next digit of our result is 3. 
Result so far: 63.0
If we take 993 away from 1165, we end up with 172.
Include the next digit (2) from the dividend after 172, then repeat: 1722 / 331

Let's proceed to step 6:
The number 331 fits into 1722 5 times, leaving a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 635.0
If we subtract 1655 from 1722, we get 67.
Bring next digit (6) of the dividend behind the 67 and repeat the process: 676 / 331

On to step 7:
The number 331 fits into 676 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 6352.0
Deduct 662 from 676 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 331

Advancing to step 8:
331 goes into 145 0 times with a remainder of 145.
Put 0 as the next digit of the answer. 
Result so far: 63520.0
If we subtract 0 from 145, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 9:
When dividing 1450 by 331, we get 4 with a remainder of 126.
Use 4 as the next digit of our solution. 
Result so far: 63520.4
The remainder is 126 after subtracting 1324 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
The number 331 fits into 1260 3 times, leaving a remainder of 267.
Record the quotient 3 as the next digit in the result. 
Result so far: 63520.43
Subtracting 993 from 1260 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 11:
If we divide 2670 by 331, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 63520.438
Subtract 2648 from 2670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
If we divide 220 by 331, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 63520.438
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 13:
2200 divided by 331 is 6 with a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 63520.43806
Subtract 1986 from 2200 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 14:
2140 divided by 331 is 6 with a remainder of 154.
Use 6 as the next digit of our solution. 
Result so far: 63520.438066
The remainder is 154 after subtracting 1986 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

In conclusion, the division gives 63520.438066 with a balance of 1.54e-05.
