We look at the division of 91854302 by 309 
The aim is to understand the frequency of 309 in 91854302.

Let's proceed to step 1:
9 divided by 309 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 309

Advancing to step 2:
309 can be fit into 91 0 times, resulting in a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 309

Step 3:
918 divided by 309 is 2 with a remainder of 300.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 618 from 918 leaves us with 300.
Take the next digit (5) from the dividend and append it to 300, then repeat: 3005 / 309

Advancing to step 4:
If we divide 3005 by 309, we get 9 and a remainder of 224.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 2781 away from 3005, we end up with 224.
Fetch the next digit (4) from the dividend, attach it to 224 and continue: 2244 / 309

Moving on to step 5:
When dividing 2244 by 309, we get 7 with a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 297.0
If we take 2163 away from 2244, we end up with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 309

Going ahead to step 6:
The number 309 fits into 813 2 times, leaving a remainder of 195.
The number 2 becomes the next digit in our result. 
Result so far: 2972.0
Subtracting 618 from 813 leaves us with 195.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 309

On to step 7:
The number 309 fits into 1950 6 times, leaving a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 29726.0
Deduct 1854 from 1950 and we're left with 96.
Fetch the next digit (2) from the dividend, attach it to 96 and continue: 962 / 309

Going ahead to step 8:
309 can be fit into 962 3 times, resulting in a remainder of 35.
The next digit of our result is 3. 
Result so far: 297263.0
If we take 927 away from 962, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
If we divide 350 by 309, we get 1 and a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 297263.1
If we subtract 309 from 350, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 10:
309 can be fit into 410 1 times, resulting in a remainder of 101.
The next digit of our result is 1. 
Result so far: 297263.11
Subtract 309 from 410 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

In conclusion, the division gives 297263.11 with a balance of 0.101.
