We divide 477458 by 21
Our goal is to divide 477458 by 21.

Advancing to step 1:
The number 21 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
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

Step 2:
47 divided by 21 is 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 5 after subtracting 42 from 47.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 21

Step 3:
21 goes into 57 2 times with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 42 away from 57, we end up with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 21

On to step 4:
The number 21 fits into 154 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 227.0
If we take 147 away from 154, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 21

On to step 5:
21 can be fit into 75 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 2273.0
If we take 63 away from 75, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 21

Going ahead to step 6:
21 can be fit into 128 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 22736.0
Deduct 126 from 128 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.

Let's proceed to step 7:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 22736.0
If we subtract 0 from 20, we 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.

Moving on to step 8:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 22736.09
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.

Moving on to step 9:
21 goes into 110 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 22736.095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 22736.0952
Deduct 42 from 50 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 21, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 22736.09523
Deduct 63 from 80 and we're left 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.

Going ahead to step 12:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 22736.095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
20 divided by 21 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 22736.095238
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 22736.09523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 22736.09523809 with a remaining 1.1e-08.
