We look at the division of 881831 by 52 
The aim is to understand the frequency of 52 in 881831.

On to step 1:
If we divide 8 by 52, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 52

Let's proceed to step 2:
52 can be fit into 88 1 times, resulting in a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 52 from 88 leaves us with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 52

Step 3:
52 can be fit into 361 6 times, resulting in a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 49 after subtracting 312 from 361.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 52

Advancing to step 4:
If we divide 498 by 52, we get 9 and a remainder of 30.
The next digit of our result is 9. 
Result so far: 169.0
The remainder is 30 after subtracting 468 from 498.
Grab the next digit (3) from the dividend, add it to 30, then carry on: 303 / 52

Advancing to step 5:
303 divided by 52 is 5 with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 1695.0
Subtracting 260 from 303 leaves us with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 52

On to step 6:
The number 52 fits into 431 8 times, leaving a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 16958.0
The remainder is 15 after subtracting 416 from 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 52 fits into 150 2 times, leaving a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 16958.2
Deduct 104 from 150 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.

Let's proceed to step 8:
52 goes into 460 8 times with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 16958.28
Subtracting 416 from 460 leaves us 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.

Going ahead to step 9:
52 goes into 440 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 16958.288
Subtract 416 from 440 to 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.

After the division, we end up with 16958.288 and a remainder of 0.0024.
