476624 divided by 21 
We want to figure out the number of times 476624 can be divided by 21.

Let's proceed to step 1:
21 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 21

Step 2:
If we divide 47 by 21, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 5 after subtracting 42 from 47.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 21

Going ahead to step 3:
56 divided by 21 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 42 away from 56, we end up with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 21

Let's proceed to step 4:
146 divided by 21 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
If we take 126 away from 146, we end up with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 21

Let's proceed to step 5:
21 can be fit into 202 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 2269.0
If we subtract 189 from 202, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 21

Step 6:
134 divided by 21 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 22696.0
If we subtract 126 from 134, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
21 goes into 80 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 22696.3
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
21 can be fit into 170 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 22696.38
Subtracting 168 from 170 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
When dividing 20 by 21, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 22696.38
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 21 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 22696.3809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
21 goes into 110 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 22696.38095
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
50 divided by 21 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 22696.380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 21 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 22696.3809523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 14:
170 divided by 21 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 22696.38095238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 22696.38095238 with a balance of 2e-09.
