We look at the division of 12339674 by 519 
We want to figure out the number of times 12339674 can be divided by 519.

Moving on to step 1:
519 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 519

Let's proceed to step 2:
519 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 519

Going ahead to step 3:
519 can be fit into 123 0 times, resulting in a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 123 to get 123.
Fetch the next digit (3) from the dividend, attach it to 123 and continue: 1233 / 519

On to step 4:
If we divide 1233 by 519, we get 2 and a remainder of 195.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 195 after subtracting 1038 from 1233.
Grab the next digit (9) from the dividend, add it to 195, then carry on: 1959 / 519

Moving on to step 5:
When dividing 1959 by 519, we get 3 with a remainder of 402.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtract 1557 from 1959 to get 402.
Fetch the next digit (6) from the dividend, attach it to 402 and continue: 4026 / 519

On to step 6:
4026 divided by 519 is 7 with a remainder of 393.
Use 7 as the next digit of our solution. 
Result so far: 237.0
If we subtract 3633 from 4026, we get 393.
Take the next digit (7) from the dividend and append it to 393, then repeat: 3937 / 519

Advancing to step 7:
The number 519 fits into 3937 7 times, leaving a remainder of 304.
The next digit of our result is 7. 
Result so far: 2377.0
If we take 3633 away from 3937, we end up with 304.
Take the next digit (4) from the dividend and append it to 304, then repeat: 3044 / 519

Let's proceed to step 8:
If we divide 3044 by 519, we get 5 and a remainder of 449.
The next digit of our result is 5. 
Result so far: 23775.0
Subtracting 2595 from 3044 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 9:
4490 divided by 519 is 8 with a remainder of 338.
The next digit of our result is 8. 
Result so far: 23775.8
Subtracting 4152 from 4490 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 10:
519 goes into 3380 6 times with a remainder of 266.
The number 6 becomes the next digit in our result. 
Result so far: 23775.86
Subtract 3114 from 3380 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 11:
2660 divided by 519 is 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 23775.865
Subtract 2595 from 2660 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
When dividing 650 by 519, we get 1 with a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 23775.8651
If we take 519 away from 650, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 13:
When dividing 1310 by 519, we get 2 with a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 23775.86512
If we subtract 1038 from 1310, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 14:
The number 519 fits into 2720 5 times, leaving a remainder of 125.
The next digit of our result is 5. 
Result so far: 23775.865125
Subtract 2595 from 2720 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 15:
519 goes into 1250 2 times with a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 23775.8651252
If we take 1038 away from 1250, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 16:
2120 divided by 519 is 4 with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 23775.86512524
Subtract 2076 from 2120 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 23775.86512524 with a remainder of 4.4e-08.
