Let's divide 40490465 by 9
The aim is to understand the frequency of 9 in 40490465.

Moving on to step 1:
9 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 9

Moving on to step 2:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 36 from 40 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 9

Moving on to step 3:
When dividing 44 by 9, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 36 from 44 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 9

Step 4:
9 can be fit into 89 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 449.0
Deduct 81 from 89 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 9

Let's proceed to step 5:
9 goes into 80 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 4498.0
The remainder is 8 after subtracting 72 from 80.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 9

Step 6:
When dividing 84 by 9, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 44989.0
Deduct 81 from 84 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 9

Going ahead to step 7:
9 can be fit into 36 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 449894.0
Subtract 36 from 36 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 9

Going ahead to step 8:
When dividing 5 by 9, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 4498940.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
9 can be fit into 50 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4498940.5
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
If we divide 50 by 9, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4498940.55
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 4498940.55 with a remainder of 0.005.
