We look at the division of 813784 by 52 
The aim is to understand the frequency of 52 in 813784.

Let's proceed to step 1:
52 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 52

Let's proceed to step 2:
When dividing 81 by 52, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 52 from 81 leaves us with 29.
Include the next digit (3) from the dividend after 29, then repeat: 293 / 52

Step 3:
The number 52 fits into 293 5 times, leaving a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 260 from 293 leaves us with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 52

Let's proceed to step 4:
If we divide 337 by 52, we get 6 and a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Subtract 312 from 337 to get 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 52

Going ahead to step 5:
When dividing 258 by 52, we get 4 with a remainder of 50.
The next digit of our result is 4. 
Result so far: 1564.0
Deduct 208 from 258 and we're left with 50.
Take the next digit (4) from the dividend and append it to 50, then repeat: 504 / 52

Step 6:
504 divided by 52 is 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 15649.0
Subtract 468 from 504 to 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.

Advancing to step 7:
If we divide 360 by 52, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 15649.6
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 15649.69
Deduct 468 from 480 and we're left 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 9:
The number 52 fits into 120 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 15649.692
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.

Advancing to step 10:
If we divide 160 by 52, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 15649.6923
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.

Advancing to step 11:
The number 52 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 15649.6923
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 12:
If we divide 400 by 52, we get 7 and a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 15649.692307
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
If we divide 360 by 52, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 15649.6923076
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
When dividing 480 by 52, we get 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 15649.69230769
If we take 468 away from 480, we end up 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.

Our division results in 15649.69230769 with a remaining 1.2e-08.
