We look at the division of 85366808 by 518 
The aim is to understand the frequency of 518 in 85366808.

Moving on to step 1:
When dividing 8 by 518, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 518

Advancing to step 2:
The number 518 fits into 85 0 times, leaving a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 518

Going ahead to step 3:
If we divide 853 by 518, we get 1 and a remainder of 335.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 335 after subtracting 518 from 853.
Include the next digit (6) from the dividend after 335, then repeat: 3356 / 518

Moving on to step 4:
3356 divided by 518 is 6 with a remainder of 248.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 3108 away from 3356, we end up with 248.
Grab the next digit (6) from the dividend, add it to 248, then carry on: 2486 / 518

On to step 5:
518 goes into 2486 4 times with a remainder of 414.
Put 4 as the next digit of the answer. 
Result so far: 164.0
The remainder is 414 after subtracting 2072 from 2486.
Bring next digit (8) of the dividend behind the 414 and repeat the process: 4148 / 518

Moving on to step 6:
If we divide 4148 by 518, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 1648.0
Subtracting 4144 from 4148 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 518

On to step 7:
518 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 16480.0
If we subtract 0 from 40, we get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 518

Moving on to step 8:
518 can be fit into 408 0 times, resulting in a remainder of 408.
The number 0 becomes the next digit in our result. 
Result so far: 164800.0
If we take 0 away from 408, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 9:
518 can be fit into 4080 7 times, resulting in a remainder of 454.
The number 7 becomes the next digit in our result. 
Result so far: 164800.7
If we take 3626 away from 4080, we end up with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 10:
If we divide 4540 by 518, we get 8 and a remainder of 396.
Record the quotient 8 as the next digit in the result. 
Result so far: 164800.78
If we subtract 4144 from 4540, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 11:
518 goes into 3960 7 times with a remainder of 334.
The next digit of our result is 7. 
Result so far: 164800.787
If we subtract 3626 from 3960, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 12:
518 can be fit into 3340 6 times, resulting in a remainder of 232.
Record the quotient 6 as the next digit in the result. 
Result so far: 164800.7876
Subtracting 3108 from 3340 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 13:
518 can be fit into 2320 4 times, resulting in a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 164800.78764
Subtracting 2072 from 2320 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 14:
If we divide 2480 by 518, we get 4 and a remainder of 408.
The next digit of our result is 4. 
Result so far: 164800.787644
If we subtract 2072 from 2480, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The quotient of the division is 164800.787644, and the remainder is 4.08e-05.
