We're dividing 819406 by 52 
The aim is to understand the frequency of 52 in 819406.

Step 1:
52 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 52

Let's proceed to step 2:
81 divided by 52 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 29 after subtracting 52 from 81.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 52

Step 3:
52 can be fit into 299 5 times, resulting in a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 260 from 299, we get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 52

Moving on to step 4:
52 goes into 394 7 times with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 157.0
If we take 364 away from 394, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 52

Advancing to step 5:
When dividing 300 by 52, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1575.0
Deduct 260 from 300 and we're left with 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 52

Going ahead to step 6:
52 goes into 406 7 times with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 15757.0
If we subtract 364 from 406, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
If we divide 420 by 52, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 15757.8
If we subtract 416 from 420, we 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 8:
52 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15757.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
52 goes into 400 7 times with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 15757.807
Deduct 364 from 400 and we're left 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.

Advancing to step 10:
If we divide 360 by 52, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 15757.8076
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.

Going ahead to step 11:
The number 52 fits into 480 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 15757.80769
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 12:
52 goes into 120 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 15757.807692
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
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: 15757.8076923
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
The number 52 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15757.8076923
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 15757.8076923 with a remaining 4e-08.
