We look at the division of 12393452 by 519 
Our goal is to divide 12393452 by 519.

Moving on to step 1:
If we divide 1 by 519, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 519

Going ahead to step 2:
519 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 519

Step 3:
123 divided by 519 is 0 with a remainder of 123.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 123 after subtracting 0 from 123.
Append the next digit (9) from the dividend to 123 and continue with: 1239 / 519

Going ahead to step 4:
When dividing 1239 by 519, we get 2 with a remainder of 201.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1038 from 1239 leaves us with 201.
Bring next digit (3) of the dividend behind the 201 and repeat the process: 2013 / 519

On to step 5:
If we divide 2013 by 519, we get 3 and a remainder of 456.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 1557 from 2013, we get 456.
Append the next digit (4) from the dividend to 456 and continue with: 4564 / 519

On to step 6:
When dividing 4564 by 519, we get 8 with a remainder of 412.
The next digit of our result is 8. 
Result so far: 238.0
If we subtract 4152 from 4564, we get 412.
Grab the next digit (5) from the dividend, add it to 412, then carry on: 4125 / 519

Going ahead to step 7:
519 goes into 4125 7 times with a remainder of 492.
Use 7 as the next digit of our solution. 
Result so far: 2387.0
If we take 3633 away from 4125, we end up with 492.
Take the next digit (2) from the dividend and append it to 492, then repeat: 4922 / 519

Let's proceed to step 8:
When dividing 4922 by 519, we get 9 with a remainder of 251.
Use 9 as the next digit of our solution. 
Result so far: 23879.0
If we subtract 4671 from 4922, we get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 9:
2510 divided by 519 is 4 with a remainder of 434.
Put 4 as the next digit of the answer. 
Result so far: 23879.4
Deduct 2076 from 2510 and we're left with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 10:
519 can be fit into 4340 8 times, resulting in a remainder of 188.
Use 8 as the next digit of our solution. 
Result so far: 23879.48
The remainder is 188 after subtracting 4152 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
If we divide 1880 by 519, we get 3 and a remainder of 323.
The number 3 becomes the next digit in our result. 
Result so far: 23879.483
If we take 1557 away from 1880, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Moving on to step 12:
If we divide 3230 by 519, we get 6 and a remainder of 116.
Record the quotient 6 as the next digit in the result. 
Result so far: 23879.4836
The remainder is 116 after subtracting 3114 from 3230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 13:
519 can be fit into 1160 2 times, resulting in a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 23879.48362
The remainder is 122 after subtracting 1038 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 14:
1220 divided by 519 is 2 with a remainder of 182.
Write down 2 as next digit of the result. 
Result so far: 23879.483622
If we subtract 1038 from 1220, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final outcome is 23879.483622, with a leftover of 1.82e-05.
