938664 divided by 52 
The aim is to understand the frequency of 52 in 938664.

Step 1:
9 divided by 52 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 52

On to step 2:
When dividing 93 by 52, we get 1 with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 52 from 93 leaves us with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 52

Going ahead to step 3:
When dividing 418 by 52, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 416 from 418, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 52

On to step 4:
52 can be fit into 26 0 times, resulting in a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 180.0
Subtract 0 from 26 to get 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 52

Going ahead to step 5:
52 goes into 266 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 1805.0
If we take 260 away from 266, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 52

On to step 6:
52 can be fit into 64 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 18051.0
Subtract 52 from 64 to get 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 7:
52 goes into 120 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 18051.2
Subtracting 104 from 120 leaves us 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.

Step 8:
52 can be fit into 160 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 18051.23
If we subtract 156 from 160, 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.

Advancing to step 9:
When dividing 40 by 52, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 18051.23
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.

Let's proceed to step 10:
52 goes into 400 7 times with a remainder of 36.
The next digit of our result is 7. 
Result so far: 18051.2307
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 11:
When dividing 360 by 52, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 18051.23076
Deduct 312 from 360 and we're left 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.

Advancing to step 12:
When dividing 480 by 52, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 18051.230769
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.

Advancing to step 13:
When dividing 120 by 52, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 18051.2307692
Subtract 104 from 120 to get 16.
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 14:
52 goes into 160 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 18051.23076923
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.

The final outcome is 18051.23076923, with a leftover of 4e-09.
