We divide 263927 by 21
We want to divide 263927 by 21.

Moving on to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

Going ahead to step 2:
The number 21 fits into 26 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 21 away from 26, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 21

Moving on to step 3:
53 divided by 21 is 2 with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 42 from 53 to get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 21

On to step 4:
119 divided by 21 is 5 with a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Subtracting 105 from 119 leaves us with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 21

On to step 5:
142 divided by 21 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1256.0
Subtracting 126 from 142 leaves us with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 21

Moving on to step 6:
The number 21 fits into 167 7 times, leaving a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 12567.0
Subtract 147 from 167 to 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.

Step 7:
200 divided by 21 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 12567.9
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
21 goes into 110 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12567.95
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.

Going ahead to step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12567.952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 12567.9523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
If we divide 170 by 21, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 12567.95238
Deduct 168 from 170 and we're left 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 12:
If we divide 20 by 21, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12567.95238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 21 is 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 12567.9523809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
When dividing 110 by 21, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12567.95238095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 12567.95238095 with a balance of 5e-09.
