115897 divided by 30 
The aim is to understand the frequency of 30 in 115897.

Going ahead to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 30

Let's proceed to step 2:
When dividing 11 by 30, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 30

Going ahead to step 3:
If we divide 115 by 30, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 25 after subtracting 90 from 115.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 30

Let's proceed to step 4:
30 can be fit into 258 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 240 away from 258, we end up with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 30

Going ahead to step 5:
189 divided by 30 is 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 386.0
The remainder is 9 after subtracting 180 from 189.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 30

Let's proceed to step 6:
When dividing 97 by 30, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3863.0
The remainder is 7 after subtracting 90 from 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
When dividing 70 by 30, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 3863.2
If we take 60 away from 70, we end up 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.

Let's proceed to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The next digit of our result is 3. 
Result so far: 3863.23
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:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3863.233
Deduct 90 from 100 and we're left 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.

Our division results in 3863.233 with a remaining 0.001.
