We're dividing 14384239 by 518 
The aim is to understand the frequency of 518 in 14384239.

Step 1:
If we divide 1 by 518, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 518

On to step 2:
When dividing 14 by 518, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 518

Moving on to step 3:
The number 518 fits into 143 0 times, leaving a remainder of 143.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 143 leaves us with 143.
Take the next digit (8) from the dividend and append it to 143, then repeat: 1438 / 518

Advancing to step 4:
If we divide 1438 by 518, we get 2 and a remainder of 402.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 402 after subtracting 1036 from 1438.
Take the next digit (4) from the dividend and append it to 402, then repeat: 4024 / 518

On to step 5:
If we divide 4024 by 518, we get 7 and a remainder of 398.
The next digit of our result is 7. 
Result so far: 27.0
If we take 3626 away from 4024, we end up with 398.
Fetch the next digit (2) from the dividend, attach it to 398 and continue: 3982 / 518

On to step 6:
518 can be fit into 3982 7 times, resulting in a remainder of 356.
Write down 7 as next digit of the result. 
Result so far: 277.0
If we take 3626 away from 3982, we end up with 356.
Grab the next digit (3) from the dividend, add it to 356, then carry on: 3563 / 518

Let's proceed to step 7:
518 can be fit into 3563 6 times, resulting in a remainder of 455.
Put 6 as the next digit of the answer. 
Result so far: 2776.0
If we take 3108 away from 3563, we end up with 455.
Fetch the next digit (9) from the dividend, attach it to 455 and continue: 4559 / 518

Going ahead to step 8:
If we divide 4559 by 518, we get 8 and a remainder of 415.
Record the quotient 8 as the next digit in the result. 
Result so far: 27768.0
Deduct 4144 from 4559 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 9:
When dividing 4150 by 518, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 27768.8
Deduct 4144 from 4150 and we're left 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.

Moving on to step 10:
When dividing 60 by 518, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 27768.8
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
If we divide 600 by 518, we get 1 and a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 27768.801
If we subtract 518 from 600, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 12:
518 can be fit into 820 1 times, resulting in a remainder of 302.
The number 1 becomes the next digit in our result. 
Result so far: 27768.8011
The remainder is 302 after subtracting 518 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

After the division, we end up with 27768.8011 and a remainder of 0.00302.
