We look at the division of 812593 by 19 
We're looking to find how many times 19 goes into 812593.

Advancing to step 1:
The number 19 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 19

Let's proceed to step 2:
If we divide 81 by 19, we get 4 and a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 76 from 81, we get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 19

On to step 3:
The number 19 fits into 52 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 38 away from 52, we end up with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 19

Step 4:
145 divided by 19 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 427.0
Deduct 133 from 145 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 19

Let's proceed to step 5:
When dividing 129 by 19, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 4276.0
If we subtract 114 from 129, we get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 19

Moving on to step 6:
The number 19 fits into 153 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 42768.0
If we subtract 152 from 153, we 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 7:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 42768.0
If we subtract 0 from 10, we 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.

Going ahead to step 8:
19 goes into 100 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 42768.05
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.

Advancing to step 9:
19 can be fit into 50 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 42768.052
If we take 38 away from 50, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 19 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 42768.0526
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.

Advancing to step 11:
The number 19 fits into 60 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 42768.05263
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.

Advancing to step 12:
19 goes into 30 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 42768.052631
Subtracting 19 from 30 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
If we divide 110 by 19, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 42768.0526315
Subtract 95 from 110 to get 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 14:
The number 19 fits into 150 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 42768.05263157
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.

After the division, we end up with 42768.05263157 and a remainder of 1.7e-08.
