We look at the division of 470647 by 21 
Let's see how many times 21 fits into 470647.

Step 1:
When dividing 4 by 21, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 21

Going ahead to step 2:
47 divided by 21 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 42 from 47 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 21

Advancing to step 3:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 42 from 50 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 21

Moving on to step 4:
When dividing 86 by 21, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
If we take 84 away from 86, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 21

Going ahead to step 5:
If we divide 24 by 21, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 2241.0
The remainder is 3 after subtracting 21 from 24.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 21

Step 6:
The number 21 fits into 37 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 22411.0
Subtracting 21 from 37 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.

Advancing to step 7:
160 divided by 21 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 22411.7
Deduct 147 from 160 and we're left 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.

On to step 8:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 22411.76
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 21, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 22411.761
If we take 21 away from 40, we end up 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.

Going ahead to step 10:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 22411.7619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
21 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 22411.7619
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 21, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 22411.761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 22411.7619047
If we subtract 147 from 160, we 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.

On to step 14:
130 divided by 21 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 22411.76190476
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 quotient of the division is 22411.76190476, and the remainder is 4e-09.
