418126 divided by 9 
The aim is to understand the frequency of 9 in 418126.

Moving on to step 1:
If we divide 4 by 9, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 9

Advancing to step 2:
When dividing 41 by 9, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 36 from 41 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 9

On to step 3:
9 goes into 58 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 46.0
The remainder is 4 after subtracting 54 from 58.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 9

Step 4:
9 can be fit into 41 4 times, resulting in a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 464.0
Subtracting 36 from 41 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 9

Moving on to step 5:
9 goes into 52 5 times with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 4645.0
Subtracting 45 from 52 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 9

Advancing to step 6:
The number 9 fits into 76 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 46458.0
If we subtract 72 from 76, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 9, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 46458.4
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
9 can be fit into 40 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 46458.44
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 46458.44 with a remainder of 0.004.
