We're dividing 48608404 by 9 
The aim is to understand the frequency of 9 in 48608404.

Advancing to step 1:
When dividing 4 by 9, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 9

On to step 2:
9 can be fit into 48 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 45 from 48 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 9

Advancing to step 3:
9 goes into 36 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 54.0
The remainder is 0 after subtracting 36 from 36.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 9

Moving on to step 4:
If we divide 0 by 9, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 540.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 9

Step 5:
9 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 5400.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 9

Moving on to step 6:
9 goes into 84 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 54009.0
If we take 81 away from 84, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 9

Advancing to step 7:
When dividing 30 by 9, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 540093.0
The remainder is 3 after subtracting 27 from 30.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 9

Let's proceed to step 8:
9 can be fit into 34 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 5400933.0
If we subtract 27 from 34, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
70 divided by 9 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 5400933.7
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
9 goes into 70 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 5400933.77
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 5400933.77 with a remaining 0.007.
