We look at the division of 472957 by 21 
We want to divide 472957 by 21.

Step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 21

On to step 2:
If we divide 47 by 21, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 42 from 47 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 21

Advancing to step 3:
If we divide 52 by 21, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 42 from 52, we get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 21

Going ahead to step 4:
If we divide 109 by 21, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
Subtracting 105 from 109 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 21

Let's proceed to step 5:
21 can be fit into 45 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2252.0
Subtract 42 from 45 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 21

Let's proceed to step 6:
21 can be fit into 37 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 22521.0
If we take 21 away from 37, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 21, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 22521.7
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 22521.76
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
21 goes into 40 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 22521.761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
When dividing 190 by 21, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 22521.7619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
21 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 22521.7619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 21, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 22521.761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 22521.7619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
21 goes into 130 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 22521.76190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 22521.76190476 with a remainder of 4e-09.
