Let's divide 403408 by 9
The aim is to understand the frequency of 9 in 403408.

On to step 1:
9 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 9

Moving on to step 2:
9 goes into 40 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 36 from 40, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 9

Let's proceed to step 3:
9 can be fit into 43 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we take 36 away from 43, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 9

Step 4:
9 goes into 74 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 448.0
The remainder is 2 after subtracting 72 from 74.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 9

On to step 5:
9 goes into 20 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 4482.0
The remainder is 2 after subtracting 18 from 20.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 9

Going ahead to step 6:
9 can be fit into 28 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 44823.0
Subtracting 27 from 28 leaves us 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.

Step 7:
9 goes into 10 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 44823.1
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.

Step 8:
When dividing 10 by 9, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 44823.11
If we subtract 9 from 10, we 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.

In conclusion, the division gives 44823.11 with a balance of 0.001.
