198723 ÷ 30 
The aim is to understand the frequency of 30 in 198723.

Step 1:
30 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 30

Step 2:
When dividing 19 by 30, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 30

Let's proceed to step 3:
30 can be fit into 198 6 times, resulting in a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 180 from 198, we get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 30

Step 4:
30 goes into 187 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 66.0
If we take 180 away from 187, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 30

Going ahead to step 5:
If we divide 72 by 30, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 662.0
If we take 60 away from 72, we end up with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 30

Going ahead to step 6:
The number 30 fits into 123 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 6624.0
The remainder is 3 after subtracting 120 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 30 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 6624.1
If we take 30 away from 30, 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.

Moving on to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6624.1
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6624.1
If we subtract 0 from 0, we get 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 final outcome is 6624.1, with a leftover of 0.0.
