We look at the division of 617489 by 9 
The aim is to understand the frequency of 9 in 617489.

Step 1:
The number 9 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 9

Moving on to step 2:
When dividing 61 by 9, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 54 from 61 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 9

Let's proceed to step 3:
The number 9 fits into 77 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 68.0
The remainder is 5 after subtracting 72 from 77.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 9

Advancing to step 4:
9 goes into 54 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 686.0
The remainder is 0 after subtracting 54 from 54.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 9

Moving on to step 5:
8 divided by 9 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 6860.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 9

On to step 6:
9 goes into 89 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 68609.0
Subtract 81 from 89 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.

Step 7:
9 goes into 80 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 68609.8
The remainder is 8 after subtracting 72 from 80.
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:
80 divided by 9 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 68609.88
If we take 72 away from 80, we end up 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.

After the division, we end up with 68609.88 and a remainder of 0.008.
