We look at the division of 519425 by 43 
We want to figure out the number of times 519425 can be divided by 43.

Advancing to step 1:
5 divided by 43 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 43

Let's proceed to step 2:
43 can be fit into 51 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 43 away from 51, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 43

Let's proceed to step 3:
When dividing 89 by 43, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 86 from 89 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 43

Let's proceed to step 4:
When dividing 34 by 43, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
Subtract 0 from 34 to get 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 43

Going ahead to step 5:
When dividing 342 by 43, we get 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 1207.0
Subtract 301 from 342 to get 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 43

Let's proceed to step 6:
The number 43 fits into 415 9 times, leaving a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 12079.0
Deduct 387 from 415 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
If we divide 280 by 43, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 12079.6
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
220 divided by 43 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 12079.65
Deduct 215 from 220 and we're left 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 9:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 12079.651
Subtracting 43 from 50 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.

Step 10:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 12079.6511
The remainder is 27 after subtracting 43 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 12079.6511 with a remainder of 0.00027.
