We're dividing 87558 by 9 
The aim is to understand the frequency of 9 in 87558.

Let's proceed to step 1:
8 divided by 9 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 9

On to step 2:
87 divided by 9 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 81 from 87 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 9

Step 3:
9 can be fit into 65 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Subtract 63 from 65 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 9

Step 4:
When dividing 25 by 9, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 972.0
Subtracting 18 from 25 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 9

Moving on to step 5:
78 divided by 9 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 9728.0
If we take 72 away from 78, we end up with 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 6:
When dividing 60 by 9, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 9728.6
If we subtract 54 from 60, 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.

On to step 7:
If we divide 60 by 9, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 9728.66
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 9728.66 with a balance of 0.006.
