Let's divide 204317 by 20
Our goal is to divide 204317 by 20.

Going ahead to step 1:
2 divided by 20 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 20

Advancing to step 2:
If we divide 20 by 20, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 20 from 20 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 20

Moving on to step 3:
If we divide 4 by 20, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 20

Moving on to step 4:
The number 20 fits into 43 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 3 after subtracting 40 from 43.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

On to step 5:
If we divide 31 by 20, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1021.0
If we subtract 20 from 31, we get 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 20

Step 6:
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: 10215.0
If we subtract 100 from 117, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
When dividing 170 by 20, we get 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 10215.8
Deduct 160 from 170 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:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10215.85
If we subtract 100 from 100, 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.

Let's proceed 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: 10215.85
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.

On to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10215.85
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 10215.85, with a leftover of 0.0.
