We divide 504268 by 20
We want to figure out the number of times 504268 can be divided by 20.

Moving on to step 1:
5 divided by 20 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 20

Going ahead to step 2:
If we divide 50 by 20, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 40 away from 50, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 20

On to step 3:
20 can be fit into 104 5 times, resulting in a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 100 from 104 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 20

Step 4:
The number 20 fits into 42 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 252.0
The remainder is 2 after subtracting 40 from 42.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 20

Advancing to step 5:
The number 20 fits into 26 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 2521.0
Subtracting 20 from 26 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 20

Going ahead to step 6:
68 divided by 20 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 25213.0
Subtract 60 from 68 to 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:
The number 20 fits into 80 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 25213.4
Subtract 80 from 80 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25213.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25213.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 25213.4, and the remainder is 0.0.
