We're dividing 243307 by 69 
The aim is to understand the frequency of 69 in 243307.

Going ahead to step 1:
The number 69 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 69

On to step 2:
If we divide 24 by 69, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 69

Moving on to step 3:
69 goes into 243 3 times with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 207 from 243 to get 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 69

On to step 4:
69 goes into 363 5 times with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 345 from 363 and we're left with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 69

Moving on to step 5:
The number 69 fits into 180 2 times, leaving a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
If we take 138 away from 180, we end up with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 69

Advancing to step 6:
The number 69 fits into 427 6 times, leaving a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 3526.0
If we take 414 away from 427, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 69 is 1 with a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 3526.1
Deduct 69 from 130 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 8:
69 goes into 610 8 times with a remainder of 58.
The next digit of our result is 8. 
Result so far: 3526.18
The remainder is 58 after subtracting 552 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
69 can be fit into 580 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 3526.188
If we subtract 552 from 580, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 3526.188, with a leftover of 0.0028.
