839336 ÷ 30 
The aim is to understand the frequency of 30 in 839336.

Going ahead to step 1:
When dividing 8 by 30, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 30

Advancing to step 2:
The number 30 fits into 83 2 times, leaving a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 60 away from 83, we end up with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 30

Let's proceed to step 3:
If we divide 239 by 30, we get 7 and a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 210 away from 239, we end up with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 30

Moving on to step 4:
30 can be fit into 293 9 times, resulting in a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 279.0
If we subtract 270 from 293, we get 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 30

Moving on to step 5:
233 divided by 30 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 2797.0
The remainder is 23 after subtracting 210 from 233.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 30

Moving on to step 6:
236 divided by 30 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 27977.0
Subtract 210 from 236 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
The number 30 fits into 260 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 27977.8
Deduct 240 from 260 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.

Advancing to step 8:
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: 27977.86
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.

Advancing to step 9:
200 divided by 30 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 27977.866
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.

The final result is 27977.866 with a remainder of 0.002.
