522815 divided by 9 
The aim is to understand the frequency of 9 in 522815.

Advancing to step 1:
The number 9 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 9

Step 2:
52 divided by 9 is 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 45 from 52 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 9

Going ahead to step 3:
The number 9 fits into 72 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 58.0
Deduct 72 from 72 and we're left with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 9

Let's proceed to step 4:
9 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 580.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 9

On to step 5:
When dividing 81 by 9, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 5809.0
Subtract 81 from 81 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 9

Let's proceed to step 6:
9 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 58090.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
9 goes into 50 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 58090.5
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.

On to step 8:
9 goes into 50 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 58090.55
If we subtract 45 from 50, we get 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 58090.55 with a remaining 0.005.
