We look at the division of 99771443 by 9 
The aim is to understand the frequency of 9 in 99771443.

Let's proceed to step 1:
9 can be fit into 9 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 9 from 9 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 9

Going ahead to step 2:
9 goes into 9 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 9

Going ahead to step 3:
9 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 9

On to step 4:
9 goes into 77 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 1108.0
If we subtract 72 from 77, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 9

Going ahead to step 5:
The number 9 fits into 51 5 times, leaving a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 11085.0
Subtracting 45 from 51 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 9

On to step 6:
If we divide 64 by 9, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 110857.0
If we take 63 away from 64, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 9

Step 7:
14 divided by 9 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1108571.0
If we subtract 9 from 14, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 9

Step 8:
If we divide 53 by 9, we get 5 and a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 11085715.0
Subtracting 45 from 53 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11085715.8
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 11085715.88
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 11085715.88, and the remainder is 0.008.
