We divide 216659 by 30
The aim is to understand the frequency of 30 in 216659.

Advancing to step 1:
2 divided by 30 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 30

Step 2:
If we divide 21 by 30, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 30

Moving on to step 3:
216 divided by 30 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 210 from 216 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 30

Let's proceed to step 4:
When dividing 66 by 30, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 72.0
If we subtract 60 from 66, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 30

Let's proceed to step 5:
If we divide 65 by 30, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 722.0
Subtracting 60 from 65 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 30

Let's proceed to step 6:
The number 30 fits into 59 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 7221.0
The remainder is 29 after subtracting 30 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
30 can be fit into 290 9 times, resulting in a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 7221.9
The remainder is 20 after subtracting 270 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 7221.96
Deduct 180 from 200 and we're left 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:
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: 7221.966
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 7221.966, with a leftover of 0.002.
