Let's divide 604423 by 20
Our goal is to divide 604423 by 20.

Going ahead to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 20

Let's proceed to step 2:
When dividing 60 by 20, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 60 from 60 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 20

Moving on to step 3:
When dividing 4 by 20, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 4 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 20

Advancing to step 4:
44 divided by 20 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 302.0
Subtracting 40 from 44 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 20

On to step 5:
The number 20 fits into 42 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 3022.0
The remainder is 2 after subtracting 40 from 42.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 20

Step 6:
When dividing 23 by 20, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 30221.0
If we subtract 20 from 23, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 20 is 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 30221.1
Deduct 20 from 30 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.

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: 30221.15
The remainder is 0 after subtracting 100 from 100.
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 30221.15
Subtracting 0 from 0 leaves us 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.

Advancing to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30221.15
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 30221.15 with a balance of 0.0.
