837383 ÷ 30 
The aim is to understand the frequency of 30 in 837383.

Step 1:
30 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 30

Moving on to step 2:
30 can be fit into 83 2 times, resulting in a remainder of 23.
The next digit of our result is 2. 
Result so far: 2.0
If we take 60 away from 83, we end up with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 30

Let's proceed to step 3:
30 can be fit into 237 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 27 after subtracting 210 from 237.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 30

Moving on to step 4:
30 can be fit into 273 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 279.0
The remainder is 3 after subtracting 270 from 273.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 30

Going ahead to step 5:
38 divided by 30 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 2791.0
If we take 30 away from 38, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 30

Step 6:
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: 27912.0
Subtracting 60 from 83 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
The number 30 fits into 230 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 27912.7
Subtracting 210 from 230 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.

Step 8:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 27912.76
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.

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: 27912.766
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 27912.766, and the remainder is 0.002.
