We divide 80866309 by 300
The aim is to understand the frequency of 300 in 80866309.

Moving on to step 1:
8 divided by 300 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 300

Let's proceed to step 2:
When dividing 80 by 300, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (8) from the dividend to 80 and continue with: 808 / 300

Let's proceed to step 3:
300 can be fit into 808 2 times, resulting in a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 600 from 808, we get 208.
Take the next digit (6) from the dividend and append it to 208, then repeat: 2086 / 300

Advancing to step 4:
If we divide 2086 by 300, we get 6 and a remainder of 286.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 1800 from 2086 and we're left with 286.
Include the next digit (6) from the dividend after 286, then repeat: 2866 / 300

Moving on to step 5:
The number 300 fits into 2866 9 times, leaving a remainder of 166.
Record the quotient 9 as the next digit in the result. 
Result so far: 269.0
Subtracting 2700 from 2866 leaves us with 166.
Bring next digit (3) of the dividend behind the 166 and repeat the process: 1663 / 300

Let's proceed to step 6:
1663 divided by 300 is 5 with a remainder of 163.
The next digit of our result is 5. 
Result so far: 2695.0
If we take 1500 away from 1663, we end up with 163.
Bring next digit (0) of the dividend behind the 163 and repeat the process: 1630 / 300

Going ahead to step 7:
If we divide 1630 by 300, we get 5 and a remainder of 130.
The next digit of our result is 5. 
Result so far: 26955.0
Subtract 1500 from 1630 to get 130.
Take the next digit (9) from the dividend and append it to 130, then repeat: 1309 / 300

Moving on to step 8:
300 goes into 1309 4 times with a remainder of 109.
Record the quotient 4 as the next digit in the result. 
Result so far: 269554.0
Deduct 1200 from 1309 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 9:
300 can be fit into 1090 3 times, resulting in a remainder of 190.
Write down 3 as next digit of the result. 
Result so far: 269554.3
Subtracting 900 from 1090 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 10:
The number 300 fits into 1900 6 times, leaving a remainder of 100.
The number 6 becomes the next digit in our result. 
Result so far: 269554.36
Subtracting 1800 from 1900 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
If we divide 1000 by 300, we get 3 and a remainder of 100.
The next digit of our result is 3. 
Result so far: 269554.363
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
If we divide 1000 by 300, we get 3 and a remainder of 100.
Write down 3 as next digit of the result. 
Result so far: 269554.3633
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 269554.3633 with a balance of 0.001.
