821924 ÷ 9 
The aim is to understand the frequency of 9 in 821924.

Advancing to step 1:
9 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 9

Advancing to step 2:
9 can be fit into 82 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 1 after subtracting 81 from 82.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 9

Advancing to step 3:
If we divide 11 by 9, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 91.0
Deduct 9 from 11 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

Moving on to step 4:
29 divided by 9 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 913.0
Subtracting 27 from 29 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 9

On to step 5:
If we divide 22 by 9, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 9132.0
Deduct 18 from 22 and we're left with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 9

Step 6:
If we divide 44 by 9, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 91324.0
Deduct 36 from 44 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 91324.8
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 9, we get 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 91324.88
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 91324.88 and a remainder of 0.008.
