88979432 ÷ 9 
The aim is to understand the frequency of 9 in 88979432.

On to step 1:
9 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 9

Moving on to step 2:
The number 9 fits into 88 9 times, leaving a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 81 from 88 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 9

Step 3:
When dividing 79 by 9, we get 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 72 from 79, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 9

Going ahead to step 4:
9 can be fit into 77 8 times, resulting in a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 988.0
The remainder is 5 after subtracting 72 from 77.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 9

On to step 5:
If we divide 59 by 9, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 9886.0
If we subtract 54 from 59, we get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 9

Going ahead to step 6:
When dividing 54 by 9, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 98866.0
Subtract 54 from 54 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 9

Let's proceed to step 7:
9 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 988660.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 9

On to step 8:
9 can be fit into 32 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 9886603.0
Subtracting 27 from 32 leaves us 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.

Going ahead to step 9:
9 can be fit into 50 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9886603.5
If we subtract 45 from 50, 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.

Let's proceed to step 10:
When dividing 50 by 9, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9886603.55
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.

The final outcome is 9886603.55, with a leftover of 0.005.
