812438 ÷ 19 
We want to divide 812438 by 19.

Advancing to step 1:
19 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 19

Let's proceed to step 2:
19 can be fit into 81 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 5 after subtracting 76 from 81.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 19

Step 3:
If we divide 52 by 19, we get 2 and 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.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 19

Step 4:
19 goes into 144 7 times with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 427.0
Subtract 133 from 144 to get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 19

On to step 5:
19 goes into 113 5 times with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 4275.0
Deduct 95 from 113 and we're left with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 19

Step 6:
If we divide 188 by 19, we get 9 and a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 42759.0
Subtracting 171 from 188 leaves us 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.

Going ahead to step 7:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 42759.8
Subtracting 152 from 170 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
180 divided by 19 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 42759.89
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 19, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 42759.894
Subtract 76 from 90 to 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 10:
19 goes into 140 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 42759.8947
Subtracting 133 from 140 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
If we divide 70 by 19, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 42759.89473
Subtract 57 from 70 to 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.

Step 12:
If we divide 130 by 19, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 42759.894736
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 13:
If we divide 160 by 19, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 42759.8947368
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.

Advancing to step 14:
19 can be fit into 80 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 42759.89473684
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.

Our division results in 42759.89473684 with a remaining 4e-09.
