We look at the division of 45628460 by 518 
The aim is to understand the frequency of 518 in 45628460.

On to step 1:
518 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 518

Step 2:
518 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 518

On to step 3:
518 can be fit into 456 0 times, resulting in a remainder of 456.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 456 and we're left with 456.
Bring next digit (2) of the dividend behind the 456 and repeat the process: 4562 / 518

On to step 4:
518 goes into 4562 8 times with a remainder of 418.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 418 after subtracting 4144 from 4562.
Grab the next digit (8) from the dividend, add it to 418, then carry on: 4188 / 518

Step 5:
4188 divided by 518 is 8 with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 4144 from 4188 to get 44.
Bring next digit (4) of the dividend behind the 44 and repeat the process: 444 / 518

Going ahead to step 6:
518 goes into 444 0 times with a remainder of 444.
The next digit of our result is 0. 
Result so far: 880.0
Subtract 0 from 444 to get 444.
Append the next digit (6) from the dividend to 444 and continue with: 4446 / 518

Going ahead to step 7:
When dividing 4446 by 518, we get 8 with a remainder of 302.
The number 8 becomes the next digit in our result. 
Result so far: 8808.0
If we subtract 4144 from 4446, we get 302.
Include the next digit (0) from the dividend after 302, then repeat: 3020 / 518

Advancing to step 8:
518 goes into 3020 5 times with a remainder of 430.
The next digit of our result is 5. 
Result so far: 88085.0
Deduct 2590 from 3020 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 9:
If we divide 4300 by 518, we get 8 and a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 88085.8
Subtract 4144 from 4300 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 10:
When dividing 1560 by 518, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 88085.83
If we take 1554 away from 1560, we end up 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.

Advancing to step 11:
When dividing 60 by 518, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 88085.83
If we take 0 away from 60, we end up 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.

Advancing to step 12:
600 divided by 518 is 1 with a remainder of 82.
The number 1 becomes the next digit in our result. 
Result so far: 88085.8301
Subtracting 518 from 600 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 13:
820 divided by 518 is 1 with a remainder of 302.
Put 1 as the next digit of the answer. 
Result so far: 88085.83011
If we take 518 away from 820, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Our division results in 88085.83011 with a remaining 0.000302.
