Let's divide 475519 by 21
We want to divide 475519 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
Subtract 0 from 4 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 21

Advancing to step 2:
The number 21 fits into 47 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 42 from 47 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 21

Step 3:
21 can be fit into 55 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 42 away from 55, we end up with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 21

Going ahead to step 4:
When dividing 135 by 21, we get 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
Subtract 126 from 135 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 21

Let's proceed to step 5:
91 divided by 21 is 4 with a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 2264.0
The remainder is 7 after subtracting 84 from 91.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 21

Advancing to step 6:
If we divide 79 by 21, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 22643.0
If we take 63 away from 79, we end up 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.

Moving on to step 7:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 22643.7
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
When dividing 130 by 21, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 22643.76
If we take 126 away from 130, we end up with 4.
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.
Use 1 as the next digit of our solution. 
Result so far: 22643.761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 22643.7619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 22643.7619
Deduct 0 from 10 and we're left 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:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 22643.761904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 22643.7619047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 22643.76190476
Subtracting 126 from 130 leaves us with 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 final result is 22643.76190476 with a remainder of 4e-09.
