Let's divide 840831 by 19
Our goal is to divide 840831 by 19.

Let's proceed to step 1:
When dividing 8 by 19, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 19

Moving on to step 2:
When dividing 84 by 19, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 76 from 84 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 19

Moving on to step 3:
The number 19 fits into 80 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 4 after subtracting 76 from 80.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 19

Going ahead to step 4:
When dividing 48 by 19, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 442.0
Subtracting 38 from 48 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 19

On to step 5:
103 divided by 19 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 4425.0
Subtract 95 from 103 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 19

Moving on to step 6:
19 goes into 81 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 44254.0
Subtracting 76 from 81 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
19 goes into 50 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 44254.2
If we subtract 38 from 50, 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.

On to step 8:
19 can be fit into 120 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 44254.26
Subtract 114 from 120 to 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.

Advancing to step 9:
19 goes into 60 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 44254.263
Deduct 57 from 60 and we're left 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 10:
The number 19 fits into 30 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 44254.2631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
The number 19 fits into 110 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 44254.26315
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
If we divide 150 by 19, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 44254.263157
Deduct 133 from 150 and we're left 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.

On to step 13:
19 goes into 170 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 44254.2631578
If we subtract 152 from 170, we 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.

On to step 14:
19 goes into 180 9 times with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 44254.26315789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 44254.26315789 with a remainder of 9e-09.
