We're dividing 68470 by 30 
The aim is to understand the frequency of 30 in 68470.

Step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 30

Let's proceed to step 2:
If we divide 68 by 30, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 8 after subtracting 60 from 68.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 30

On to step 3:
The number 30 fits into 84 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 60 from 84 to get 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 30

Going ahead to step 4:
If we divide 247 by 30, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Deduct 240 from 247 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 30

Step 5:
The number 30 fits into 70 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2282.0
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 6:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 2282.3
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 2282.33
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 2282.33, with a leftover of 0.01.
