80969165 divided by 243 
The aim is to understand the frequency of 243 in 80969165.

Step 1:
243 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 243

On to step 2:
243 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 243

Going ahead to step 3:
When dividing 809 by 243, we get 3 with a remainder of 80.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 729 from 809 leaves us with 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 243

Moving on to step 4:
If we divide 806 by 243, we get 3 and a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 729 from 806, we get 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 243

On to step 5:
243 can be fit into 779 3 times, resulting in a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 333.0
The remainder is 50 after subtracting 729 from 779.
Include the next digit (1) from the dividend after 50, then repeat: 501 / 243

Going ahead to step 6:
When dividing 501 by 243, we get 2 with a remainder of 15.
The next digit of our result is 2. 
Result so far: 3332.0
If we take 486 away from 501, we end up with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 243

Going ahead to step 7:
243 goes into 156 0 times with a remainder of 156.
Write down 0 as next digit of the result. 
Result so far: 33320.0
Subtracting 0 from 156 leaves us with 156.
Append the next digit (5) from the dividend to 156 and continue with: 1565 / 243

Advancing to step 8:
If we divide 1565 by 243, we get 6 and a remainder of 107.
Record the quotient 6 as the next digit in the result. 
Result so far: 333206.0
The remainder is 107 after subtracting 1458 from 1565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 9:
If we divide 1070 by 243, we get 4 and a remainder of 98.
Record the quotient 4 as the next digit in the result. 
Result so far: 333206.4
If we subtract 972 from 1070, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 10:
243 can be fit into 980 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 333206.44
Subtract 972 from 980 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 333206.44 with a remainder of 0.008.
