475268 ÷ 21 
We want to figure out the number of times 475268 can be divided by 21.

Going ahead to step 1:
If we divide 4 by 21, we get 0 and 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.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 21

Step 2:
When dividing 47 by 21, we get 2 with 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.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 21

Advancing to step 3:
21 can be fit into 55 2 times, resulting in a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 13 after subtracting 42 from 55.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 21

Moving on to step 4:
21 goes into 132 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 226.0
Subtracting 126 from 132 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 21

Moving on to step 5:
The number 21 fits into 66 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2263.0
Subtract 63 from 66 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 21

Moving on to step 6:
If we divide 38 by 21, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 22631.0
Deduct 21 from 38 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 7:
170 divided by 21 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 22631.8
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.

Let's proceed to step 8:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 22631.8
If we take 0 away from 20, we end up 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.

Advancing to step 9:
When dividing 200 by 21, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 22631.809
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 10:
110 divided by 21 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 22631.8095
Deduct 105 from 110 and we're left 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.

Advancing to step 11:
50 divided by 21 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 22631.80952
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.

Moving on to step 12:
The number 21 fits into 80 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 22631.809523
The remainder is 17 after subtracting 63 from 80.
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 13:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 22631.8095238
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.

Let's proceed to step 14:
21 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 22631.8095238
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.

In conclusion, the division gives 22631.8095238 with a balance of 2e-08.
