We look at the division of 70365884 by 30 
The aim is to understand the frequency of 30 in 70365884.

Let's proceed to step 1:
30 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 30

Going ahead to step 2:
The number 30 fits into 70 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 60 from 70 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 30

On to step 3:
If we divide 103 by 30, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 90 from 103 leaves us with 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 30

Step 4:
When dividing 136 by 30, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 234.0
If we subtract 120 from 136, we get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 30

Let's proceed to step 5:
The number 30 fits into 165 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2345.0
Subtracting 150 from 165 leaves us with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 30

Moving on to step 6:
30 goes into 158 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 23455.0
Subtracting 150 from 158 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 30

Going ahead to step 7:
If we divide 88 by 30, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 234552.0
Subtract 60 from 88 to get 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 30

Step 8:
284 divided by 30 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 2345529.0
The remainder is 14 after subtracting 270 from 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
The number 30 fits into 140 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 2345529.4
If we subtract 120 from 140, we 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.

Going ahead to step 10:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 2345529.46
Subtracting 180 from 200 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 11:
30 can be fit into 200 6 times, resulting in a remainder of 20.
The next digit of our result is 6. 
Result so far: 2345529.466
Subtracting 180 from 200 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.

The final result is 2345529.466 with a remainder of 0.002.
