825146 ÷ 30 
The aim is to understand the frequency of 30 in 825146.

Step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 30

Let's proceed to step 2:
If we divide 82 by 30, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 60 away from 82, we end up with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 30

Step 3:
30 can be fit into 225 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtract 210 from 225 to get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 30

Moving on to step 4:
When dividing 151 by 30, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 275.0
If we subtract 150 from 151, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 30

Advancing to step 5:
14 divided by 30 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 2750.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 30

Step 6:
146 divided by 30 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 27504.0
The remainder is 26 after subtracting 120 from 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
30 can be fit into 260 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 27504.8
If we subtract 240 from 260, 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 8:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 27504.86
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.

Let's proceed to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 27504.866
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.

The quotient of the division is 27504.866, and the remainder is 0.002.
