We look at the division of 858338 by 19 
Let's see how many times 19 fits into 858338.

Going ahead to step 1:
If we divide 8 by 19, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 19

Going ahead to step 2:
19 goes into 85 4 times with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 76 from 85 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 19

Going ahead to step 3:
19 can be fit into 98 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 95 from 98 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 19

Let's proceed to step 4:
When dividing 33 by 19, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 451.0
If we subtract 19 from 33, we get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 19

Going ahead to step 5:
19 can be fit into 143 7 times, resulting in a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 4517.0
If we take 133 away from 143, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 19

Step 6:
19 goes into 108 5 times with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 45175.0
If we subtract 95 from 108, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 19, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 45175.6
If we subtract 114 from 130, we 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 8:
19 can be fit into 160 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 45175.68
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.

Advancing to step 9:
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: 45175.684
Subtracting 76 from 80 leaves us 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.

Going ahead to step 10:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 45175.6842
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.

Going ahead to step 11:
If we divide 20 by 19, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 45175.68421
Subtracting 19 from 20 leaves us with 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:
10 divided by 19 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 45175.68421
Deduct 0 from 10 and we're left 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.

On to step 13:
The number 19 fits into 100 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 45175.6842105
If we take 95 away from 100, we end up 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.

Moving on to step 14:
When dividing 50 by 19, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 45175.68421052
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 final outcome is 45175.68421052, with a leftover of 1.2e-08.
