We look at the division of 504203 by 19 
Our goal is to divide 504203 by 19.

On to step 1:
If we divide 5 by 19, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 19

Advancing to step 2:
The number 19 fits into 50 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 38 away from 50, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 19

Advancing to step 3:
19 goes into 124 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 114 from 124 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 19

Going ahead to step 4:
When dividing 102 by 19, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 265.0
The remainder is 7 after subtracting 95 from 102.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 19

Moving on to step 5:
When dividing 70 by 19, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 2653.0
If we subtract 57 from 70, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 19

Step 6:
133 divided by 19 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 26537.0
If we subtract 133 from 133, 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 7:
0 divided by 19 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26537.0
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.

Let's proceed to step 8:
19 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26537.0
Subtract 0 from 0 to 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.

The final result is 26537.0 with a remainder of 0.0.
