We're dividing 268079 by 21 
Our goal is to divide 268079 by 21.

Step 1:
2 divided by 21 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 21

Moving on to step 2:
21 can be fit into 26 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 5 after subtracting 21 from 26.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 21

Moving on to step 3:
The number 21 fits into 58 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 42 from 58 leaves us with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 21

Moving on to step 4:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 127.0
Subtracting 147 from 160 leaves us with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 21

Step 5:
The number 21 fits into 137 6 times, leaving a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 1276.0
If we subtract 126 from 137, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 21

Going ahead to step 6:
21 can be fit into 119 5 times, resulting in a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 12765.0
Subtract 105 from 119 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
21 can be fit into 140 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 12765.6
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
140 divided by 21 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 12765.66
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 12765.66 with a balance of 0.014.
