We divide 647284 by 9
The aim is to understand the frequency of 9 in 647284.

Let's proceed to step 1:
9 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 9

Step 2:
9 goes into 64 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 63 from 64 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 9

Let's proceed to step 3:
If we divide 17 by 9, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 71.0
The remainder is 8 after subtracting 9 from 17.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 9

Advancing to step 4:
9 can be fit into 82 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 719.0
Subtracting 81 from 82 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 9

Step 5:
When dividing 18 by 9, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 7192.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 9

Advancing to step 6:
9 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 71920.0
If we subtract 0 from 4, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 9, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 71920.4
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 9 fits into 40 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 71920.44
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 71920.44, with a leftover of 0.004.
