21106729 ÷ 265 
Let's see how many times 265 fits into 21106729.

Moving on to step 1:
When dividing 2 by 265, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 265

Going ahead to step 2:
265 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 265

Going ahead to step 3:
265 goes into 211 0 times with a remainder of 211.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 211, we end up with 211.
Fetch the next digit (0) from the dividend, attach it to 211 and continue: 2110 / 265

Step 4:
265 goes into 2110 7 times with a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 1855 from 2110, we get 255.
Bring next digit (6) of the dividend behind the 255 and repeat the process: 2556 / 265

Step 5:
The number 265 fits into 2556 9 times, leaving a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtract 2385 from 2556 to get 171.
Bring next digit (7) of the dividend behind the 171 and repeat the process: 1717 / 265

Step 6:
1717 divided by 265 is 6 with a remainder of 127.
The next digit of our result is 6. 
Result so far: 796.0
If we subtract 1590 from 1717, we get 127.
Grab the next digit (2) from the dividend, add it to 127, then carry on: 1272 / 265

Advancing to step 7:
If we divide 1272 by 265, we get 4 and a remainder of 212.
Put 4 as the next digit of the answer. 
Result so far: 7964.0
Subtract 1060 from 1272 to get 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 265

Going ahead to step 8:
If we divide 2129 by 265, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 79648.0
Subtract 2120 from 2129 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
When dividing 90 by 265, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 79648.0
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
The number 265 fits into 900 3 times, leaving a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 79648.03
The remainder is 105 after subtracting 795 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 11:
If we divide 1050 by 265, we get 3 and a remainder of 255.
Use 3 as the next digit of our solution. 
Result so far: 79648.033
Deduct 795 from 1050 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final result is 79648.033 with a remainder of 0.0255.
