Let's divide 86150812 by 300
The aim is to understand the frequency of 300 in 86150812.

Step 1:
300 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 300

On to step 2:
When dividing 86 by 300, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 300

Moving on to step 3:
When dividing 861 by 300, we get 2 with a remainder of 261.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 600 away from 861, we end up with 261.
Include the next digit (5) from the dividend after 261, then repeat: 2615 / 300

Step 4:
300 can be fit into 2615 8 times, resulting in a remainder of 215.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 2400 from 2615, we get 215.
Bring next digit (0) of the dividend behind the 215 and repeat the process: 2150 / 300

Advancing to step 5:
When dividing 2150 by 300, we get 7 with a remainder of 50.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
Subtracting 2100 from 2150 leaves us with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 300

Let's proceed to step 6:
300 goes into 508 1 times with a remainder of 208.
The next digit of our result is 1. 
Result so far: 2871.0
The remainder is 208 after subtracting 300 from 508.
Take the next digit (1) from the dividend and append it to 208, then repeat: 2081 / 300

On to step 7:
300 can be fit into 2081 6 times, resulting in a remainder of 281.
Put 6 as the next digit of the answer. 
Result so far: 28716.0
If we subtract 1800 from 2081, we get 281.
Append the next digit (2) from the dividend to 281 and continue with: 2812 / 300

Moving on to step 8:
2812 divided by 300 is 9 with a remainder of 112.
Put 9 as the next digit of the answer. 
Result so far: 287169.0
If we subtract 2700 from 2812, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
300 can be fit into 1120 3 times, resulting in a remainder of 220.
Record the quotient 3 as the next digit in the result. 
Result so far: 287169.3
Subtract 900 from 1120 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
When dividing 2200 by 300, we get 7 with a remainder of 100.
Put 7 as the next digit of the answer. 
Result so far: 287169.37
Deduct 2100 from 2200 and we're left 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.

Advancing to step 11:
When dividing 1000 by 300, we get 3 with a remainder of 100.
The number 3 becomes the next digit in our result. 
Result so far: 287169.373
If we take 900 away from 1000, we end up 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.

Moving on to step 12:
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: 287169.3733
Deduct 900 from 1000 and we're left 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.

Our division results in 287169.3733 with a remaining 0.001.
