We divide 216246 by 30
The aim is to understand the frequency of 30 in 216246.

Advancing to step 1:
2 divided by 30 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 30

Going ahead to step 2:
30 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 30

Step 3:
216 divided by 30 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 210 from 216, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 30

Step 4:
62 divided by 30 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 60 from 62 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 30

Moving on to step 5:
The number 30 fits into 24 0 times, leaving a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 720.0
If we subtract 0 from 24, we get 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 30

Advancing to step 6:
The number 30 fits into 246 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 7208.0
If we subtract 240 from 246, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 30, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 7208.2
The remainder is 0 after subtracting 60 from 60.
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 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7208.2
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.

Advancing to step 9:
0 divided by 30 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7208.2
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.

Our division results in 7208.2 with a remaining 0.0.
