361575 ÷ 9 
The aim is to understand the frequency of 9 in 361575.

Going ahead to step 1:
3 divided by 9 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 9

Step 2:
9 goes into 36 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 36 from 36 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 9

Let's proceed to step 3:
9 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 9

Moving on to step 4:
The number 9 fits into 15 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 401.0
The remainder is 6 after subtracting 9 from 15.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 9

On to step 5:
9 goes into 67 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 4017.0
Subtract 63 from 67 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 9

Let's proceed to step 6:
If we divide 45 by 9, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 40175.0
The remainder is 0 after subtracting 45 from 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
9 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 40175.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
9 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40175.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 40175.0 with a remaining 0.0.
