111904 ÷ 9 
The aim is to understand the frequency of 9 in 111904.

Going ahead to step 1:
9 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 9

Let's proceed to step 2:
If we divide 11 by 9, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 9 from 11.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 9

On to step 3:
9 can be fit into 21 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 18 from 21 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 9

Let's proceed to step 4:
9 goes into 39 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we take 36 away from 39, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Step 5:
9 can be fit into 30 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 1243.0
If we subtract 27 from 30, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 9

Going ahead to step 6:
9 goes into 34 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 12433.0
If we subtract 27 from 34, 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.

Step 7:
The number 9 fits into 70 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 12433.7
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:
The number 9 fits into 70 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 12433.77
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 12433.77 with a remaining 0.007.
