505531 divided by 20 
Our goal is to divide 505531 by 20.

Going ahead 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
The remainder is 5 after subtracting 0 from 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 20

Moving on to step 2:
20 can be fit into 50 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 40 from 50 to get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 20

Advancing to step 3:
When dividing 105 by 20, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 5 after subtracting 100 from 105.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 20

Let's proceed to step 4:
The number 20 fits into 55 2 times, leaving a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 252.0
Deduct 40 from 55 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 20

Moving on to step 5:
The number 20 fits into 153 7 times, leaving a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 2527.0
If we take 140 away from 153, we end up with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 20

Going ahead to step 6:
20 goes into 131 6 times with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 25276.0
If we subtract 120 from 131, we get 11.
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 7:
When dividing 110 by 20, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 25276.5
Deduct 100 from 110 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.

Let's proceed to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 25276.55
Subtracting 100 from 100 leaves us 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.

The quotient of the division is 25276.55, and the remainder is 0.0.
