We look at the division of 863052 by 19 
Let's see how many times 19 fits into 863052.

Step 1:
8 divided by 19 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 19

Advancing to step 2:
86 divided by 19 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 76 from 86 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 19

Step 3:
The number 19 fits into 103 5 times, leaving a remainder of 8.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 95 from 103 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 19

Advancing to step 4:
19 can be fit into 80 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
If we take 76 away from 80, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 19

On to step 5:
If we divide 45 by 19, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 4542.0
If we subtract 38 from 45, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 19

Moving on to step 6:
When dividing 72 by 19, we get 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 45423.0
The remainder is 15 after subtracting 57 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
19 goes into 150 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 45423.7
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
The number 19 fits into 170 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 45423.78
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.

Going ahead to step 9:
When dividing 180 by 19, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 45423.789
Deduct 171 from 180 and we're left 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.

Moving on to step 10:
If we divide 90 by 19, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 45423.7894
If we subtract 76 from 90, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
19 goes into 140 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 45423.78947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
19 can be fit into 70 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 45423.789473
If we take 57 away from 70, we end up 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.

Step 13:
When dividing 130 by 19, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 45423.7894736
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 14:
19 goes into 160 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 45423.78947368
Subtract 152 from 160 to 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.

After the division, we end up with 45423.78947368 and a remainder of 8e-09.
