999002 ÷ 9 
The aim is to understand the frequency of 9 in 999002.

Advancing to step 1:
9 can be fit into 9 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 9 from 9, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 9

Advancing to step 2:
If we divide 9 by 9, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 9

Moving on to step 3:
The number 9 fits into 9 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 111.0
If we subtract 9 from 9, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 9

Let's proceed to step 4:
0 divided by 9 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1110.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 9

Advancing to step 5:
If we divide 0 by 9, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11100.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 9

Step 6:
If we divide 2 by 9, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 111000.0
Deduct 0 from 2 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.

Moving on to step 7:
The number 9 fits into 20 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 111000.2
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.

On to step 8:
9 can be fit into 20 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 111000.22
Subtracting 18 from 20 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.

The quotient of the division is 111000.22, and the remainder is 0.002.
