82548720 ÷ 9 
The aim is to understand the frequency of 9 in 82548720.

Going ahead to step 1:
9 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 9

On to step 2:
The number 9 fits into 82 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 81 from 82 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 9

On to step 3:
If we divide 15 by 9, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 9 from 15, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 9

Let's proceed to step 4:
When dividing 64 by 9, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 917.0
Subtract 63 from 64 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 9

Step 5:
9 can be fit into 18 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 9172.0
If we subtract 18 from 18, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 9

Let's proceed to step 6:
9 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 91720.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 9

Advancing to step 7:
The number 9 fits into 72 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 917208.0
Subtract 72 from 72 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 9

Moving on to step 8:
The number 9 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9172080.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
When dividing 0 by 9, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9172080.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
9 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9172080.0
If we take 0 away from 0, we end up with 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 final result is 9172080.0 with a remainder of 0.0.
