Let's divide 90839292 by 30
The aim is to understand the frequency of 30 in 90839292.

Step 1:
The number 30 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 30

Step 2:
The number 30 fits into 90 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 90 from 90 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 30

Going ahead to step 3:
8 divided by 30 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 30.0
If we take 0 away from 8, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 30

Moving on to step 4:
When dividing 83 by 30, we get 2 with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 302.0
If we subtract 60 from 83, we get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 30

Moving on to step 5:
When dividing 239 by 30, we get 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 3027.0
Subtracting 210 from 239 leaves us with 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 30

Step 6:
When dividing 292 by 30, we get 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 30279.0
Subtract 270 from 292 to get 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 30

On to step 7:
When dividing 229 by 30, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 302797.0
Subtracting 210 from 229 leaves us with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 30

Moving on to step 8:
30 can be fit into 192 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 3027976.0
Subtracting 180 from 192 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
30 goes into 120 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 3027976.4
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 30 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3027976.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3027976.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 3027976.4, and the remainder is 0.0.
