We're dividing 768343 by 19 
Let's see how many times 19 fits into 768343.

Advancing to step 1:
19 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 19

Advancing to step 2:
If we divide 76 by 19, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 76 from 76 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 19

Let's proceed to step 3:
When dividing 8 by 19, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 40.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 19

Let's proceed to step 4:
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: 404.0
If we subtract 76 from 83, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 19

Moving on to step 5:
If we divide 74 by 19, we get 3 and a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 4043.0
Deduct 57 from 74 and we're left with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 19

Step 6:
If we divide 173 by 19, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 40439.0
Deduct 171 from 173 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.

Moving on to step 7:
When dividing 20 by 19, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 40439.1
If we subtract 19 from 20, 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.

Advancing to step 8:
The number 19 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 40439.1
If we take 0 away from 10, we end up 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.

Going ahead to step 9:
19 goes into 100 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 40439.105
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.

Going ahead to step 10:
When dividing 50 by 19, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 40439.1052
The remainder is 12 after subtracting 38 from 50.
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 11:
19 goes into 120 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 40439.10526
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
19 goes into 60 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 40439.105263
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
If we divide 30 by 19, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 40439.1052631
If we take 19 away from 30, we end up 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.

Moving on to step 14:
110 divided by 19 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 40439.10526315
Subtracting 95 from 110 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 40439.10526315, with a leftover of 1.5e-08.
