We look at the division of 539553 by 52 
The aim is to understand the frequency of 52 in 539553.

Step 1:
If we divide 5 by 52, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 52

Advancing to step 2:
52 goes into 53 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 52 from 53, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 52

Let's proceed to step 3:
52 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 19, we get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 52

Let's proceed to step 4:
If we divide 195 by 52, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 103.0
The remainder is 39 after subtracting 156 from 195.
Bring next digit (5) of the dividend behind the 39 and repeat the process: 395 / 52

Advancing to step 5:
52 can be fit into 395 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 1037.0
Deduct 364 from 395 and we're left with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 52

Moving on to step 6:
313 divided by 52 is 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 10376.0
If we subtract 312 from 313, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 52, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10376.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
52 goes into 100 1 times with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 10376.01
The remainder is 48 after subtracting 52 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 10376.019
Subtracting 468 from 480 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 52, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 10376.0192
Deduct 104 from 120 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
When dividing 160 by 52, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 10376.01923
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
40 divided by 52 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10376.01923
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 10376.0192307
If we subtract 364 from 400, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
If we divide 360 by 52, we get 6 and a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 10376.01923076
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 10376.01923076 with a remainder of 4.8e-08.
