We divide 80202924 by 9
The aim is to understand the frequency of 9 in 80202924.

Advancing to step 1:
When dividing 8 by 9, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 9

Going ahead to step 2:
9 can be fit into 80 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 72 from 80 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 9

On to step 3:
9 goes into 82 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 81 from 82 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 9

Moving on to step 4:
9 can be fit into 10 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 891.0
Subtract 9 from 10 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 9

Going ahead to step 5:
9 goes into 12 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 8911.0
Subtracting 9 from 12 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 9

Advancing to step 6:
The number 9 fits into 39 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 89114.0
The remainder is 3 after subtracting 36 from 39.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 9

Advancing to step 7:
If we divide 32 by 9, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 891143.0
Deduct 27 from 32 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 9

On to step 8:
If we divide 54 by 9, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 8911436.0
If we subtract 54 from 54, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
9 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8911436.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8911436.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 8911436.0, and the remainder is 0.0.
