We look at the division of 667258 by 52 
The aim is to understand the frequency of 52 in 667258.

Advancing to step 1:
52 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 52

On to step 2:
52 can be fit into 66 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 52 from 66 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 52

Moving on to step 3:
The number 52 fits into 147 2 times, leaving a remainder of 43.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 104 from 147 leaves us with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 52

Going ahead to step 4:
If we divide 432 by 52, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 128.0
The remainder is 16 after subtracting 416 from 432.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 52

Let's proceed to step 5:
The number 52 fits into 165 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 1283.0
Subtracting 156 from 165 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 52

Moving on to step 6:
The number 52 fits into 98 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 12831.0
Deduct 52 from 98 and we're left 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:
When dividing 460 by 52, we get 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 12831.8
Deduct 416 from 460 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
The number 52 fits into 440 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 12831.88
If we subtract 416 from 440, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 12831.88 with a remaining 0.024.
