We look at the division of 38709185 by 30 
The aim is to understand the frequency of 30 in 38709185.

Advancing to step 1:
3 divided by 30 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 30

Advancing to step 2:
When dividing 38 by 30, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 30 from 38 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 30

Going ahead to step 3:
The number 30 fits into 87 2 times, leaving a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 60 away from 87, we end up with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 30

Going ahead to step 4:
If we divide 270 by 30, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we subtract 270 from 270, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 30

Moving on to step 5:
If we divide 9 by 30, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 1290.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 30

Step 6:
If we divide 91 by 30, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 12903.0
Subtract 90 from 91 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 30

Going ahead to step 7:
If we divide 18 by 30, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 129030.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 30

Moving on to step 8:
30 goes into 185 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 1290306.0
If we take 180 away from 185, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 30 fits into 50 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1290306.1
Deduct 30 from 50 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.

Going ahead to step 10:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1290306.16
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.

Going ahead to step 11:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 1290306.166
Subtract 180 from 200 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.

After the division, we end up with 1290306.166 and a remainder of 0.002.
