We're dividing 556763 by 21 
Let's see how many times 21 fits into 556763.

Step 1:
21 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 21

Advancing to step 2:
55 divided by 21 is 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 42 from 55 leaves us with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 21

Step 3:
21 can be fit into 136 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 10 after subtracting 126 from 136.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 21

Let's proceed to step 4:
If we divide 107 by 21, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
Subtracting 105 from 107 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 21

Let's proceed to step 5:
When dividing 26 by 21, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 2651.0
If we take 21 away from 26, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 21

Step 6:
The number 21 fits into 53 2 times, leaving a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 26512.0
If we take 42 away from 53, 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.

Moving on to step 7:
110 divided by 21 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 26512.5
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.

Step 8:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 26512.52
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.

Advancing to step 9:
If we divide 80 by 21, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 26512.523
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.

Moving on to step 10:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 26512.5238
Subtract 168 from 170 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 26512.5238
Subtracting 0 from 20 leaves us 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.

On to step 12:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 26512.523809
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.

Step 13:
21 goes into 110 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 26512.5238095
If we subtract 105 from 110, we 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.

Step 14:
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: 26512.52380952
If we subtract 42 from 50, we 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.

In conclusion, the division gives 26512.52380952 with a balance of 8e-09.
