We divide 873344 by 9
The aim is to understand the frequency of 9 in 873344.

Advancing to step 1:
If we divide 8 by 9, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 9

Step 2:
87 divided by 9 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 81 from 87 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 9

On to step 3:
When dividing 63 by 9, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 63 from 63 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 9

Step 4:
9 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 970.0
If we subtract 0 from 3, we get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 9

Step 5:
9 goes into 34 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 9703.0
Subtracting 27 from 34 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 9

Advancing to step 6:
74 divided by 9 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 97038.0
Subtracting 72 from 74 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 9 fits into 20 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 97038.2
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 9, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 97038.22
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 97038.22 with a remainder of 0.002.
