148317 ÷ 30 
The aim is to understand the frequency of 30 in 148317.

Let's proceed to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 30

On to step 2:
30 goes into 14 0 times with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 30

Moving on to step 3:
The number 30 fits into 148 4 times, leaving a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 120 from 148 and we're left with 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 30

On to step 4:
283 divided by 30 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtracting 270 from 283 leaves us with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 30

Going ahead to step 5:
131 divided by 30 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 494.0
The remainder is 11 after subtracting 120 from 131.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 30

Step 6:
117 divided by 30 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 4943.0
Deduct 90 from 117 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
If we divide 270 by 30, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 4943.9
The remainder is 0 after subtracting 270 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4943.9
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4943.9
If we take 0 away from 0, we end up with 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 4943.9, and the remainder is 0.0.
