We look at the division of 532503 by 9 
The aim is to understand the frequency of 9 in 532503.

Step 1:
When dividing 5 by 9, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 9

Moving on to step 2:
9 goes into 53 5 times with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 45 from 53 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 9

Step 3:
82 divided by 9 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 59.0
If we take 81 away from 82, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 9

Advancing to step 4:
15 divided by 9 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 591.0
If we subtract 9 from 15, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 9

On to step 5:
60 divided by 9 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 5916.0
Deduct 54 from 60 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 9

Going ahead to step 6:
9 goes into 63 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 59167.0
Deduct 63 from 63 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.

Let's proceed to step 7:
When dividing 0 by 9, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 59167.0
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.

On to step 8:
9 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 59167.0
The remainder is 0 after subtracting 0 from 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 outcome is 59167.0, with a leftover of 0.0.
