We're dividing 729488 by 9 
The aim is to understand the frequency of 9 in 729488.

Step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 9

Going ahead to step 2:
9 goes into 72 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 72 from 72 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 9

Moving on to step 3:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Subtract 9 from 9 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 9

Let's proceed to step 4:
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: 810.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 9

Moving on to step 5:
48 divided by 9 is 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 8105.0
Subtracting 45 from 48 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 9

Advancing to step 6:
The number 9 fits into 38 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 81054.0
Subtracting 36 from 38 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
If we divide 20 by 9, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 81054.2
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 9, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 81054.22
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 81054.22, and the remainder is 0.002.
