We look at the division of 472008 by 21 
We're looking to find how many times 21 goes into 472008.

Advancing to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 21

Going ahead to step 2:
21 goes into 47 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 42 from 47 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 21

Step 3:
If we divide 52 by 21, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 42 from 52, we get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 21

On to step 4:
100 divided by 21 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 224.0
If we take 84 away from 100, we end up with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 21

Going ahead to step 5:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 2247.0
Subtracting 147 from 160 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 21

Going ahead to step 6:
138 divided by 21 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 22476.0
Subtracting 126 from 138 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
21 goes into 120 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 22476.5
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 22476.57
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 21, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 22476.571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 10:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 22476.5714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 22476.57142
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 22476.571428
If we take 168 away from 180, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
21 goes into 120 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 22476.5714285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 22476.57142857
If we subtract 147 from 150, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 22476.57142857, and the remainder is 3e-09.
