80771 divided by 9 
The aim is to understand the frequency of 9 in 80771.

Moving on to step 1:
If we divide 8 by 9, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 9

Going ahead to step 2:
When dividing 80 by 9, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 72 from 80 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 9

Let's proceed to step 3:
When dividing 87 by 9, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 81 from 87 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 9

Step 4:
If we divide 67 by 9, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 897.0
If we subtract 63 from 67, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 9

Advancing to step 5:
If we divide 41 by 9, we get 4 and a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 8974.0
Deduct 36 from 41 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 6:
When dividing 50 by 9, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8974.5
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8974.55
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 8974.55 with a remaining 0.005.
