We're dividing 43915678 by 519 
We want to divide 43915678 by 519.

Moving on to step 1:
519 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 519

Step 2:
519 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 519

Advancing to step 3:
519 can be fit into 439 0 times, resulting in a remainder of 439.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 439 to get 439.
Fetch the next digit (1) from the dividend, attach it to 439 and continue: 4391 / 519

Going ahead to step 4:
When dividing 4391 by 519, we get 8 with a remainder of 239.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 4152 from 4391 and we're left with 239.
Fetch the next digit (5) from the dividend, attach it to 239 and continue: 2395 / 519

Let's proceed to step 5:
2395 divided by 519 is 4 with a remainder of 319.
The next digit of our result is 4. 
Result so far: 84.0
Subtract 2076 from 2395 to get 319.
Take the next digit (6) from the dividend and append it to 319, then repeat: 3196 / 519

Step 6:
The number 519 fits into 3196 6 times, leaving a remainder of 82.
The next digit of our result is 6. 
Result so far: 846.0
If we take 3114 away from 3196, we end up with 82.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 519

Moving on to step 7:
827 divided by 519 is 1 with a remainder of 308.
Put 1 as the next digit of the answer. 
Result so far: 8461.0
The remainder is 308 after subtracting 519 from 827.
Fetch the next digit (8) from the dividend, attach it to 308 and continue: 3088 / 519

Step 8:
3088 divided by 519 is 5 with a remainder of 493.
Put 5 as the next digit of the answer. 
Result so far: 84615.0
If we subtract 2595 from 3088, we get 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

On to step 9:
519 can be fit into 4930 9 times, resulting in a remainder of 259.
The next digit of our result is 9. 
Result so far: 84615.9
If we subtract 4671 from 4930, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Step 10:
519 goes into 2590 4 times with a remainder of 514.
Record the quotient 4 as the next digit in the result. 
Result so far: 84615.94
The remainder is 514 after subtracting 2076 from 2590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 11:
The number 519 fits into 5140 9 times, leaving a remainder of 469.
The number 9 becomes the next digit in our result. 
Result so far: 84615.949
The remainder is 469 after subtracting 4671 from 5140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Let's proceed to step 12:
If we divide 4690 by 519, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 84615.9499
The remainder is 19 after subtracting 4671 from 4690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 84615.9499, with a leftover of 0.00019.
