We're dividing 476882 by 21 
We want to figure out the number of times 476882 can be divided by 21.

Step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 21

Let's proceed to step 2:
21 can be fit into 47 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 42 from 47 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 21

Advancing to step 3:
21 goes into 56 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 14 after subtracting 42 from 56.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 21

Step 4:
148 divided by 21 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
The remainder is 1 after subtracting 147 from 148.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 21

Step 5:
When dividing 18 by 21, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 2270.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 21

Going ahead to step 6:
When dividing 182 by 21, we get 8 with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 22708.0
If we subtract 168 from 182, we 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.

Going ahead to step 7:
If we divide 140 by 21, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 22708.6
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.

Step 8:
When dividing 140 by 21, we get 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 22708.66
If we subtract 126 from 140, we 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 22708.66 with a balance of 0.014.
