We look at the division of 803410 by 19 
Let's see how many times 19 fits into 803410.

On to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 19

On to step 2:
When dividing 80 by 19, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 76 from 80, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 19

Let's proceed to step 3:
When dividing 43 by 19, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 5 after subtracting 38 from 43.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 19

Let's proceed to step 4:
If we divide 54 by 19, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 422.0
If we subtract 38 from 54, we get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 19

Moving on to step 5:
161 divided by 19 is 8 with a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 4228.0
The remainder is 9 after subtracting 152 from 161.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 19

Advancing to step 6:
If we divide 90 by 19, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 42284.0
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
19 goes into 140 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 42284.7
Subtracting 133 from 140 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
If we divide 70 by 19, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 42284.73
Deduct 57 from 70 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
If we divide 130 by 19, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 42284.736
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 19 fits into 160 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 42284.7368
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
80 divided by 19 is 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 42284.73684
Subtract 76 from 80 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
When dividing 40 by 19, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 42284.736842
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
20 divided by 19 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 42284.7368421
Subtract 19 from 20 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 14:
10 divided by 19 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 42284.7368421
If we take 0 away from 10, we end up 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.

The final result is 42284.7368421 with a remainder of 1e-08.
