We look at the division of 216970 by 9 
The aim is to understand the frequency of 9 in 216970.

Going ahead to step 1:
If we divide 2 by 9, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 9

Going ahead to step 2:
When dividing 21 by 9, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 18 from 21, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 9

Let's proceed to step 3:
The number 9 fits into 36 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 0 after subtracting 36 from 36.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 9

Let's proceed to step 4:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 241.0
Subtracting 9 from 9 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 9

Moving on to step 5:
When dividing 7 by 9, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 2410.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 9

On to step 6:
When dividing 70 by 9, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 24107.0
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
9 can be fit into 70 7 times, resulting in a remainder of 7.
The next digit of our result is 7. 
Result so far: 24107.7
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
70 divided by 9 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 24107.77
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 24107.77 with a balance of 0.007.
