We're dividing 27457771 by 30 
The aim is to understand the frequency of 30 in 27457771.

Going ahead to step 1:
When dividing 2 by 30, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 30

Advancing to step 2:
27 divided by 30 is 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 30

On to step 3:
30 can be fit into 274 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 270 from 274 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 30

Moving on to step 4:
30 goes into 45 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Subtracting 30 from 45 leaves us with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 30

Moving on to step 5:
The number 30 fits into 157 5 times, leaving a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 915.0
If we subtract 150 from 157, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 30

Going ahead to step 6:
When dividing 77 by 30, we get 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 9152.0
The remainder is 17 after subtracting 60 from 77.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 30

On to step 7:
If we divide 177 by 30, we get 5 and a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 91525.0
If we take 150 away from 177, we end up with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 30

Going ahead to step 8:
30 goes into 271 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 915259.0
Subtracting 270 from 271 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 30 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 915259.0
Subtract 0 from 10 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.

Moving on to step 10:
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: 915259.03
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.

Step 11:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 915259.033
The remainder is 10 after subtracting 90 from 100.
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 915259.033 with a remaining 0.001.
