We look at the division of 439816 by 19 
Let's see how many times 19 fits into 439816.

Advancing to step 1:
4 divided by 19 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 19

Let's proceed to step 2:
43 divided by 19 is 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 38 from 43, we get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 19

Let's proceed to step 3:
When dividing 59 by 19, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 57 from 59, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 19

On to step 4:
The number 19 fits into 28 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 231.0
Subtracting 19 from 28 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 19

Let's proceed to step 5:
When dividing 91 by 19, we get 4 with a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 2314.0
The remainder is 15 after subtracting 76 from 91.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 19

Going ahead to step 6:
19 can be fit into 156 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 23148.0
The remainder is 4 after subtracting 152 from 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 19, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 23148.2
Subtracting 38 from 40 leaves us 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 8:
When dividing 20 by 19, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 23148.21
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.

Let's proceed to step 9:
10 divided by 19 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 23148.21
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.

On to step 10:
19 goes into 100 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 23148.2105
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.

Step 11:
19 goes into 50 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 23148.21052
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.

Advancing to step 12:
19 goes into 120 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 23148.210526
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
19 can be fit into 60 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 23148.2105263
If we subtract 57 from 60, we 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.

Step 14:
When dividing 30 by 19, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 23148.21052631
Deduct 19 from 30 and we're left 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.

The final result is 23148.21052631 with a remainder of 1.1e-08.
