We look at the division of 839091 by 19 
We want to figure out the number of times 839091 can be divided by 19.

Advancing to step 1:
The number 19 fits into 8 0 times, leaving 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 (3) from the dividend after 8, then repeat: 83 / 19

Going ahead to step 2:
If we divide 83 by 19, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 7 after subtracting 76 from 83.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 19

Going ahead to step 3:
19 can be fit into 79 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtract 76 from 79 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 19

Let's proceed to step 4:
30 divided by 19 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 441.0
Deduct 19 from 30 and we're left with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 19

Going ahead to step 5:
19 goes into 119 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 4416.0
Deduct 114 from 119 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 19

Step 6:
19 goes into 51 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 44162.0
Subtracting 38 from 51 leaves us 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.

Moving on to step 7:
19 goes into 130 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 44162.6
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.

Let's proceed to step 8:
160 divided by 19 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 44162.68
If we subtract 152 from 160, we get 8.
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 9:
If we divide 80 by 19, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 44162.684
Deduct 76 from 80 and we're left 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.

Step 10:
40 divided by 19 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 44162.6842
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 11:
19 goes into 20 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 44162.68421
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 12:
19 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 44162.68421
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
19 can be fit into 100 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 44162.6842105
If we subtract 95 from 100, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 44162.68421052
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.

The quotient of the division is 44162.68421052, and the remainder is 1.2e-08.
