We look at the division of 126767 by 21 
We're looking to find how many times 21 goes into 126767.

Moving on to step 1:
The number 21 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 21

Moving on to step 2:
When dividing 12 by 21, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 21

On to step 3:
21 can be fit into 126 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 126 from 126, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 21

Moving on to step 4:
The number 21 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 21

Moving on to step 5:
The number 21 fits into 76 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 603.0
Subtracting 63 from 76 leaves us with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 21

Going ahead to step 6:
The number 21 fits into 137 6 times, leaving a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 6036.0
If we subtract 126 from 137, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 21, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 6036.5
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 21, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 6036.52
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
21 goes into 80 3 times with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 6036.523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
If we divide 170 by 21, we get 8 and a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 6036.5238
If we take 168 away from 170, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
21 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6036.5238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
When dividing 200 by 21, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 6036.523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 13:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6036.5238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 6036.52380952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 6036.52380952 with a balance of 8e-09.
