392671 ÷ 9 
The aim is to understand the frequency of 9 in 392671.

Advancing to step 1:
If we divide 3 by 9, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 9

Step 2:
The number 9 fits into 39 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 36 from 39 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 9

Let's proceed to step 3:
The number 9 fits into 32 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 27 from 32, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 9

Step 4:
56 divided by 9 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
If we subtract 54 from 56, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 9

Let's proceed to step 5:
9 goes into 27 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 4363.0
If we take 27 away from 27, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 9

Moving on to step 6:
If we divide 1 by 9, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 43630.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 9 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 43630.1
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
10 divided by 9 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 43630.11
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 43630.11 with a remainder of 0.001.
