868273 ÷ 30 
The aim is to understand the frequency of 30 in 868273.

Let's proceed to step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 30

Let's proceed to step 2:
If we divide 86 by 30, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 60 from 86 to get 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 30

On to step 3:
268 divided by 30 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 240 from 268 leaves us with 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 30

Going ahead to step 4:
30 goes into 282 9 times with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 289.0
Subtract 270 from 282 to get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 30

Step 5:
When dividing 127 by 30, we get 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 2894.0
If we subtract 120 from 127, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 30

Going ahead to step 6:
If we divide 73 by 30, we get 2 and a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 28942.0
Deduct 60 from 73 and we're left 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.

Moving on to step 7:
When dividing 130 by 30, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 28942.4
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 30 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 28942.43
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 28942.433
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 28942.433, with a leftover of 0.001.
