We're dividing 64209 by 52 
The aim is to understand the frequency of 52 in 64209.

Let's proceed to step 1:
The number 52 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 52

Moving on to step 2:
64 divided by 52 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 52 from 64 and we're left with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 52

Going ahead to step 3:
52 can be fit into 122 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 104 away from 122, we end up with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 52

Let's proceed to step 4:
If we divide 180 by 52, we get 3 and a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we take 156 away from 180, we end up with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 52

Let's proceed to step 5:
When dividing 249 by 52, we get 4 with a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 1234.0
Deduct 208 from 249 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 6:
The number 52 fits into 410 7 times, leaving a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 1234.7
Subtracting 364 from 410 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
52 can be fit into 460 8 times, resulting in a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 1234.78
Subtract 416 from 460 to get 44.
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 8:
If we divide 440 by 52, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1234.788
Deduct 416 from 440 and we're left 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.

In conclusion, the division gives 1234.788 with a balance of 0.0024.
