We look at the division of 806239 by 19 
We're looking to find how many times 19 goes into 806239.

Step 1:
If we divide 8 by 19, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 19

Let's proceed to step 2:
When dividing 80 by 19, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 76 from 80 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 19

On to step 3:
The number 19 fits into 46 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtract 38 from 46 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 19

Moving on to step 4:
The number 19 fits into 82 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 424.0
If we subtract 76 from 82, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 19

Moving on to step 5:
The number 19 fits into 63 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 4243.0
The remainder is 6 after subtracting 57 from 63.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 19

Advancing to step 6:
When dividing 69 by 19, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 42433.0
If we subtract 57 from 69, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 19 is 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 42433.6
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
19 goes into 60 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 42433.63
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
19 can be fit into 30 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 42433.631
Subtract 19 from 30 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
19 goes into 110 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 42433.6315
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
The number 19 fits into 150 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 42433.63157
If we take 133 away from 150, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
If we divide 170 by 19, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 42433.631578
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
19 goes into 180 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 42433.6315789
Subtracting 171 from 180 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 14:
If we divide 90 by 19, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 42433.63157894
Deduct 76 from 90 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 42433.63157894, and the remainder is 1.4e-08.
