173183 ÷ 30 
The aim is to understand the frequency of 30 in 173183.

Going ahead to step 1:
If we divide 1 by 30, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 30

Moving on to step 2:
17 divided by 30 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 30

Moving on to step 3:
173 divided by 30 is 5 with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 23 after subtracting 150 from 173.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 30

On to step 4:
30 goes into 231 7 times with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 210 from 231 to get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 30

Step 5:
The number 30 fits into 218 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 577.0
Deduct 210 from 218 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 30

Moving on to step 6:
When dividing 83 by 30, we get 2 with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 5772.0
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.

Let's proceed to step 7:
The number 30 fits into 230 7 times, leaving a remainder of 20.
The next digit of our result is 7. 
Result so far: 5772.7
If we take 210 away from 230, 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 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 5772.76
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.

Moving on to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 5772.766
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.

After the division, we end up with 5772.766 and a remainder of 0.002.
