Let's divide 216234 by 9
The aim is to understand the frequency of 9 in 216234.

On to step 1:
If we divide 2 by 9, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 9

On to step 2:
9 goes into 21 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 18 away from 21, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 9

Moving on to step 3:
When dividing 36 by 9, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 36 from 36 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 9

Going ahead to step 4:
2 divided by 9 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 240.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 9

Advancing to step 5:
The number 9 fits into 23 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2402.0
Deduct 18 from 23 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 9

On to step 6:
The number 9 fits into 54 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 24026.0
If we subtract 54 from 54, 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.

Moving on to step 7:
When dividing 0 by 9, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24026.0
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.

Moving on to step 8:
When dividing 0 by 9, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24026.0
Subtracting 0 from 0 leaves us 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.

The final result is 24026.0 with a remainder of 0.0.
