506 divided by 20 
We're looking to find how many times 20 goes into 506.

Moving on to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 20

Moving on to step 2:
20 goes into 50 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 40 from 50 leaves us with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 20

Let's proceed to step 3:
The number 20 fits into 106 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 100 away from 106, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 4:
When dividing 60 by 20, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 25.3
If we take 60 away from 60, we end up 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.

Let's proceed to step 5:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25.3
Subtracting 0 from 0 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.

On to step 6:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25.3
If we take 0 away from 0, we end up 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.

After the division, we end up with 25.3 and a remainder of 0.0.
