517660 ÷ 52 
The aim is to understand the frequency of 52 in 517660.

Step 1:
52 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 52

Advancing to step 2:
When dividing 51 by 52, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 52

Going ahead to step 3:
If we divide 517 by 52, we get 9 and a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 468 from 517, we get 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 52

Moving on to step 4:
52 can be fit into 496 9 times, resulting in a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 468 from 496, we get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 52

Let's proceed to step 5:
When dividing 286 by 52, we get 5 with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 995.0
Subtracting 260 from 286 leaves us with 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 52

Step 6:
When dividing 260 by 52, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 9955.0
Subtract 260 from 260 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 52 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9955.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 52 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9955.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 9955.0 with a remaining 0.0.
