We divide 554288 by 9
The aim is to understand the frequency of 9 in 554288.

Going ahead 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
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 9

Let's proceed to step 2:
9 goes into 55 6 times with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 54 from 55 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 9

Going ahead to step 3:
9 goes into 14 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 61.0
The remainder is 5 after subtracting 9 from 14.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 9

Step 4:
52 divided by 9 is 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 615.0
Subtracting 45 from 52 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 9

Let's proceed to step 5:
The number 9 fits into 78 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 6158.0
The remainder is 6 after subtracting 72 from 78.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 9

Step 6:
68 divided by 9 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 61587.0
If we take 63 away from 68, 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.

Moving on to step 7:
9 goes into 50 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 61587.5
Subtract 45 from 50 to 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.

Let's proceed to step 8:
When dividing 50 by 9, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 61587.55
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 61587.55 with a remaining 0.005.
