125795 divided by 30 
The aim is to understand the frequency of 30 in 125795.

On to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 30

Moving on to step 2:
When dividing 12 by 30, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 30

On to step 3:
When dividing 125 by 30, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 5 after subtracting 120 from 125.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 30

Advancing to step 4:
The number 30 fits into 57 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Deduct 30 from 57 and we're left with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 30

Let's proceed to step 5:
279 divided by 30 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 419.0
The remainder is 9 after subtracting 270 from 279.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 30

Moving on to step 6:
30 goes into 95 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 4193.0
Subtract 90 from 95 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 30 fits into 50 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 4193.1
Subtract 30 from 50 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 4193.16
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 4193.166
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 4193.166, with a leftover of 0.002.
