We're dividing 505725 by 20 
We want to figure out the number of times 505725 can be divided by 20.

Step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 20

On to step 2:
When dividing 50 by 20, we get 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 40 from 50 and we're left with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 20

Going ahead to step 3:
20 goes into 105 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 100 from 105, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 20

Advancing to step 4:
If we divide 57 by 20, we get 2 and a remainder of 17.
The next digit of our result is 2. 
Result so far: 252.0
If we take 40 away from 57, we end up with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 20

Going ahead to step 5:
20 can be fit into 172 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 2528.0
If we subtract 160 from 172, we get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 20

Moving on to step 6:
125 divided by 20 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 25286.0
If we take 120 away from 125, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 20 fits into 50 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 25286.2
Subtracting 40 from 50 leaves us 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:
20 goes into 100 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 25286.25
Subtract 100 from 100 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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 25286.25
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25286.25
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.

The final outcome is 25286.25, with a leftover of 0.0.
