We divide 604317 by 20
We want to divide 604317 by 20.

Going ahead to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 20

Going ahead to step 2:
60 divided by 20 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 60 from 60 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 20

On to step 3:
The number 20 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 20

Going ahead to step 4:
When dividing 43 by 20, we get 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 302.0
If we subtract 40 from 43, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

Let's proceed to step 5:
31 divided by 20 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 3021.0
Subtracting 20 from 31 leaves us with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 20

Moving on to step 6:
20 can be fit into 117 5 times, resulting in a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 30215.0
Subtract 100 from 117 to 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.

Step 7:
If we divide 170 by 20, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 30215.8
If we subtract 160 from 170, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 30215.85
If we take 100 away from 100, 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.

Step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30215.85
Deduct 0 from 0 and we're left 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.

Going ahead to step 10:
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: 30215.85
The remainder is 0 after subtracting 0 from 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 30215.85, with a leftover of 0.0.
