We look at the division of 83193681 by 9 
The aim is to understand the frequency of 9 in 83193681.

Step 1:
If we divide 8 by 9, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 9

Step 2:
83 divided by 9 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 81 away from 83, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 9

Step 3:
If we divide 21 by 9, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 92.0
The remainder is 3 after subtracting 18 from 21.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 9

Let's proceed to step 4:
If we divide 39 by 9, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 924.0
Subtracting 36 from 39 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 9

On to step 5:
33 divided by 9 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 9243.0
Deduct 27 from 33 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 9

Moving on to step 6:
If we divide 66 by 9, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 92437.0
Subtracting 63 from 66 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 9

Advancing to step 7:
When dividing 38 by 9, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 924374.0
If we take 36 away from 38, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 9

Moving on to step 8:
9 goes into 21 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 9243742.0
Deduct 18 from 21 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
30 divided by 9 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 9243742.3
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
30 divided by 9 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 9243742.33
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

After the division, we end up with 9243742.33 and a remainder of 0.003.
