We divide 505772 by 20
Let's see how many times 20 fits into 505772.

On to step 1:
5 divided by 20 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 20

Advancing to step 2:
50 divided by 20 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 40 from 50 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 20

On to step 3:
If we divide 105 by 20, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 100 away from 105, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 20

Moving on to step 4:
If we divide 57 by 20, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 252.0
Deduct 40 from 57 and we're left with 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 20

Advancing to step 5:
The number 20 fits into 177 8 times, leaving a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 2528.0
If we subtract 160 from 177, we get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 20

On to step 6:
20 goes into 172 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 25288.0
If we subtract 160 from 172, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 20, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 25288.6
If we subtract 120 from 120, 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.

Moving on to step 8:
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: 25288.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25288.6
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 final outcome is 25288.6, with a leftover of 0.0.
