517305 ÷ 20 
Our goal is to divide 517305 by 20.

On to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 20

Moving on to step 2:
If we divide 51 by 20, we get 2 and a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 40 from 51 and we're left with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 20

Going ahead to step 3:
20 can be fit into 117 5 times, resulting in a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 100 from 117 to get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 20

Going ahead to step 4:
The number 20 fits into 173 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
If we take 160 away from 173, we end up with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 20

Let's proceed to step 5:
130 divided by 20 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 2586.0
If we take 120 away from 130, we end up with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 20

Let's proceed to step 6:
20 goes into 105 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 25865.0
Subtract 100 from 105 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
20 goes into 50 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 25865.2
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.

On to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25865.25
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25865.25
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.

Going ahead to step 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25865.25
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.

In conclusion, the division gives 25865.25 with a balance of 0.0.
