Let's divide 604304 by 20
We want to divide 604304 by 20.

Step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 20

Going ahead to step 2:
20 goes into 60 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 0 after subtracting 60 from 60.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 20

Let's proceed to step 3:
20 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 20

Let's proceed to step 4:
When dividing 43 by 20, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 302.0
Subtracting 40 from 43 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 20

Moving on to step 5:
When dividing 30 by 20, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 3021.0
If we subtract 20 from 30, we get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 20

Moving on to step 6:
When dividing 104 by 20, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 30215.0
Subtracting 100 from 104 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 30215.2
The remainder is 0 after subtracting 40 from 40.
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 8:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30215.2
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.

Step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30215.2
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 30215.2, with a leftover of 0.0.
