835469 ÷ 30 
The aim is to understand the frequency of 30 in 835469.

On to step 1:
8 divided by 30 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 30

Advancing to step 2:
30 can be fit into 83 2 times, resulting in a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 60 from 83 leaves us with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 30

Let's proceed to step 3:
235 divided by 30 is 7 with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 210 from 235 to get 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 30

Advancing to step 4:
30 goes into 254 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 278.0
If we subtract 240 from 254, we get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 30

Moving on to step 5:
30 can be fit into 146 4 times, resulting in a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2784.0
Subtract 120 from 146 to get 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 30

Moving on to step 6:
269 divided by 30 is 8 with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 27848.0
Deduct 240 from 269 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
30 can be fit into 290 9 times, resulting in a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 27848.9
Subtract 270 from 290 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.

Step 8:
200 divided by 30 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 27848.96
If we take 180 away from 200, we end up 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.

Step 9:
30 goes into 200 6 times with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 27848.966
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 27848.966 and a remainder of 0.002.
