611268 ÷ 21 
We want to figure out the number of times 611268 can be divided by 21.

On to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 21

Let's proceed to step 2:
21 can be fit into 61 2 times, resulting in a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 19 after subtracting 42 from 61.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 21

Step 3:
21 goes into 191 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 189 from 191 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 21

Step 4:
21 goes into 22 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 291.0
Subtracting 21 from 22 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 21

On to step 5:
21 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 2910.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 21

Going ahead to step 6:
168 divided by 21 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 29108.0
Subtract 168 from 168 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 21, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 29108.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 21, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 29108.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 29108.0 with a balance of 0.0.
