We look at the division of 274054 by 30 
The aim is to understand the frequency of 30 in 274054.

On to step 1:
The number 30 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 30

Advancing to step 2:
The number 30 fits into 27 0 times, leaving a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 30

Advancing to step 3:
The number 30 fits into 274 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 4 after subtracting 270 from 274.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 30

Moving on to step 4:
40 divided by 30 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 30 from 40 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 30

Going ahead to step 5:
105 divided by 30 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 913.0
Subtract 90 from 105 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 30

Going ahead to step 6:
30 goes into 154 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 9135.0
The remainder is 4 after subtracting 150 from 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
30 goes into 40 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 9135.1
Subtracting 30 from 40 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.

Moving on to step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 9135.13
If we take 90 away from 100, 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.

On to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 9135.133
If we subtract 90 from 100, we 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.

After the division, we end up with 9135.133 and a remainder of 0.001.
