Let's divide 89870333 by 9
The aim is to understand the frequency of 9 in 89870333.

Going ahead to step 1:
The number 9 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 9

Step 2:
The number 9 fits into 89 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 9.0
If we take 81 away from 89, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 9

Moving on to step 3:
The number 9 fits into 88 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 81 from 88, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 9

Step 4:
If we divide 77 by 9, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 998.0
Deduct 72 from 77 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 9

On to step 5:
The number 9 fits into 50 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9985.0
If we subtract 45 from 50, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 9

Let's proceed to step 6:
The number 9 fits into 53 5 times, leaving a remainder of 8.
The next digit of our result is 5. 
Result so far: 99855.0
The remainder is 8 after subtracting 45 from 53.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 9

Step 7:
83 divided by 9 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 998559.0
Subtract 81 from 83 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 9

Step 8:
When dividing 23 by 9, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 9985592.0
If we subtract 18 from 23, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9985592.5
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
When dividing 50 by 9, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9985592.55
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 9985592.55 with a balance of 0.005.
