We look at the division of 503084 by 20 
We want to figure out the number of times 503084 can be divided by 20.

Step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 20

On to step 2:
20 can be fit into 50 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 40 from 50, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 20

Let's proceed to step 3:
20 can be fit into 103 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 100 from 103, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 20

Step 4:
When dividing 30 by 20, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
If we take 20 away from 30, we end up with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 20

Moving on to step 5:
20 goes into 108 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 2515.0
Subtracting 100 from 108 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 20

On to step 6:
20 goes into 84 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 25154.0
If we take 80 away from 84, we end up 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.

Moving on to step 7:
20 goes into 40 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 25154.2
If we take 40 away from 40, 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.

Let's proceed to step 8:
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: 25154.2
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 25154.2
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 result is 25154.2 with a remainder of 0.0.
