We look at the division of 65872 by 69 
The aim is to understand the frequency of 69 in 65872.

Step 1:
69 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 69

On to step 2:
69 goes into 65 0 times with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 69

Step 3:
When dividing 658 by 69, we get 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 621 from 658, we get 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 69

Advancing to step 4:
69 can be fit into 377 5 times, resulting in a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtracting 345 from 377 leaves us with 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 69

Step 5:
If we divide 322 by 69, we get 4 and a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 954.0
The remainder is 46 after subtracting 276 from 322.
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 6:
If we divide 460 by 69, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 954.6
If we take 414 away from 460, we end up 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.

Advancing to step 7:
69 can be fit into 460 6 times, resulting in a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 954.66
The remainder is 46 after subtracting 414 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 954.66 and a remainder of 0.046.
