We're dividing 759272 by 30 
The aim is to understand the frequency of 30 in 759272.

On to step 1:
If we divide 7 by 30, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 30

Step 2:
30 goes into 75 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 60 from 75 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 30

On to step 3:
When dividing 159 by 30, we get 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 150 from 159 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 30

Moving on to step 4:
92 divided by 30 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 253.0
If we subtract 90 from 92, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 30

Going ahead to step 5:
30 can be fit into 27 0 times, resulting in a remainder of 27.
The next digit of our result is 0. 
Result so far: 2530.0
If we subtract 0 from 27, we get 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 30

Step 6:
30 can be fit into 272 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 25309.0
Subtracting 270 from 272 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 30 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25309.0
Subtracting 0 from 20 leaves us 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 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 25309.06
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
30 goes into 200 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 25309.066
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 result is 25309.066 with a remainder of 0.002.
