We're dividing 472612 by 21 
We want to divide 472612 by 21.

Advancing to step 1:
4 divided by 21 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 21

Step 2:
21 can be fit into 47 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 47, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 21

Moving on to step 3:
When dividing 52 by 21, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 42 from 52 to get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 21

On to step 4:
If we divide 106 by 21, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 225.0
Deduct 105 from 106 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 21

Let's proceed to step 5:
21 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 2250.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 21

Advancing to step 6:
The number 21 fits into 112 5 times, leaving a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 22505.0
If we take 105 away from 112, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
21 goes into 70 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 22505.3
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
21 can be fit into 70 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 22505.33
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 22505.33, with a leftover of 0.007.
