553805 divided by 9 
The aim is to understand the frequency of 9 in 553805.

Let's proceed to step 1:
5 divided by 9 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 9

On to step 2:
9 goes into 55 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 54 from 55 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 9

Step 3:
When dividing 13 by 9, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 9 from 13 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 9

Step 4:
9 goes into 48 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 615.0
The remainder is 3 after subtracting 45 from 48.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 9

Step 5:
If we divide 30 by 9, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6153.0
The remainder is 3 after subtracting 27 from 30.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 9

Going ahead to step 6:
When dividing 35 by 9, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 61533.0
If we subtract 27 from 35, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
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: 61533.8
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 61533.88
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 61533.88, with a leftover of 0.008.
