We look at the division of 21080838 by 264 
We want to divide 21080838 by 264.

Advancing to step 1:
264 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 264

On to step 2:
If we divide 21 by 264, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 264

Let's proceed to step 3:
The number 264 fits into 210 0 times, leaving a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Include the next digit (8) from the dividend after 210, then repeat: 2108 / 264

Advancing to step 4:
264 can be fit into 2108 7 times, resulting in a remainder of 260.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 1848 from 2108 and we're left with 260.
Append the next digit (0) from the dividend to 260 and continue with: 2600 / 264

Let's proceed to step 5:
When dividing 2600 by 264, we get 9 with a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtract 2376 from 2600 to get 224.
Append the next digit (8) from the dividend to 224 and continue with: 2248 / 264

Step 6:
If we divide 2248 by 264, we get 8 and a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 798.0
Subtracting 2112 from 2248 leaves us with 136.
Include the next digit (3) from the dividend after 136, then repeat: 1363 / 264

Let's proceed to step 7:
264 can be fit into 1363 5 times, resulting in a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 7985.0
Deduct 1320 from 1363 and we're left with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 264

Let's proceed to step 8:
When dividing 438 by 264, we get 1 with a remainder of 174.
Write down 1 as next digit of the result. 
Result so far: 79851.0
If we subtract 264 from 438, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 9:
264 goes into 1740 6 times with a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 79851.6
If we subtract 1584 from 1740, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 10:
The number 264 fits into 1560 5 times, leaving a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 79851.65
If we subtract 1320 from 1560, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
264 can be fit into 2400 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 79851.659
Subtract 2376 from 2400 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
264 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 79851.659
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 13:
264 goes into 2400 9 times with a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 79851.65909
The remainder is 24 after subtracting 2376 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
If we divide 240 by 264, we get 0 and a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 79851.65909
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 15:
264 can be fit into 2400 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 79851.6590909
Subtracting 2376 from 2400 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 16:
The number 264 fits into 240 0 times, leaving a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 79851.6590909
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 79851.6590909, with a leftover of 2.4e-07.
