We look at the division of 520327 by 52 
The aim is to understand the frequency of 52 in 520327.

Going ahead to step 1:
5 divided by 52 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 52

On to step 2:
When dividing 52 by 52, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 52 from 52.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 52

Step 3:
52 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 52

Step 4:
If we divide 3 by 52, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 52

Moving on to step 5:
32 divided by 52 is 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 1000.0
If we take 0 away from 32, we end up with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 52

Step 6:
327 divided by 52 is 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 10006.0
If we subtract 312 from 327, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
52 goes into 150 2 times with a remainder of 46.
The next digit of our result is 2. 
Result so far: 10006.2
Subtract 104 from 150 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
When dividing 460 by 52, we get 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 10006.28
The remainder is 44 after subtracting 416 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
52 goes into 440 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10006.288
If we take 416 away from 440, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 10006.288 with a remaining 0.0024.
