30851157 ÷ 9 
The aim is to understand the frequency of 9 in 30851157.

Going ahead to step 1:
When dividing 3 by 9, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 9

Advancing to step 2:
If we divide 30 by 9, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 27 from 30 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 9

Advancing to step 3:
When dividing 38 by 9, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 34.0
If we take 36 away from 38, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 9

Let's proceed to step 4:
When dividing 25 by 9, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
Subtracting 18 from 25 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 9

Going ahead to step 5:
The number 9 fits into 71 7 times, leaving a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 3427.0
Deduct 63 from 71 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 9

Moving on to step 6:
When dividing 81 by 9, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 34279.0
Subtracting 81 from 81 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 9

Moving on to step 7:
When dividing 5 by 9, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 342790.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 9

Going ahead to step 8:
57 divided by 9 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 3427906.0
The remainder is 3 after subtracting 54 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
The number 9 fits into 30 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3427906.3
Subtract 27 from 30 to get 3.
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.
Use 3 as the next digit of our solution. 
Result so far: 3427906.33
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.

The final result is 3427906.33 with a remainder of 0.003.
