259949 ÷ 9 
The aim is to understand the frequency of 9 in 259949.

Let's proceed to step 1:
If we divide 2 by 9, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 9

Advancing to step 2:
When dividing 25 by 9, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 18 from 25 and we're left with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 9

Step 3:
9 can be fit into 79 8 times, resulting in a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 72 from 79 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 9

Let's proceed to step 4:
The number 9 fits into 79 8 times, leaving a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 288.0
If we take 72 away from 79, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 9

On to step 5:
9 goes into 74 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2888.0
Subtract 72 from 74 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 9

Step 6:
29 divided by 9 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 28883.0
Subtracting 27 from 29 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:
20 divided by 9 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 28883.2
The remainder is 2 after subtracting 18 from 20.
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:
20 divided by 9 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 28883.22
If we take 18 away from 20, we end up 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.

After the division, we end up with 28883.22 and a remainder of 0.002.
