We divide 475806 by 21
We want to divide 475806 by 21.

Advancing to step 1:
4 divided by 21 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 21

Moving on to step 2:
When dividing 47 by 21, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 42 from 47 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 21

Advancing to step 3:
The number 21 fits into 55 2 times, leaving a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 42 from 55 to get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 21

Going ahead to step 4:
21 goes into 138 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 226.0
The remainder is 12 after subtracting 126 from 138.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 21

Let's proceed to step 5:
120 divided by 21 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2265.0
If we subtract 105 from 120, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 21

Advancing to step 6:
The number 21 fits into 156 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 22657.0
Deduct 147 from 156 and we're left 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.

On to step 7:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 22657.4
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 22657.42
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 22657.428
Subtracting 168 from 180 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.

Going ahead to step 10:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 22657.4285
If we subtract 105 from 120, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
If we divide 150 by 21, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 22657.42857
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.

On to step 12:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 22657.428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 22657.4285714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
When dividing 60 by 21, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 22657.42857142
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 22657.42857142 with a balance of 1.8e-08.
