725642 ÷ 30 
The aim is to understand the frequency of 30 in 725642.

Going ahead to step 1:
7 divided by 30 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 30

Advancing to step 2:
30 goes into 72 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 60 from 72, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 30

Going ahead to step 3:
When dividing 125 by 30, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 120 from 125 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 30

Step 4:
When dividing 56 by 30, we get 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 241.0
Deduct 30 from 56 and we're left with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 30

Let's proceed to step 5:
If we divide 264 by 30, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 2418.0
If we take 240 away from 264, we end up with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 30

Let's proceed to step 6:
If we divide 242 by 30, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 24188.0
If we subtract 240 from 242, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 30, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 24188.0
If we take 0 away from 20, 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:
When dividing 200 by 30, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 24188.06
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 30 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 24188.066
The remainder is 20 after subtracting 180 from 200.
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 outcome is 24188.066, with a leftover of 0.002.
