We divide 728708 by 9
The aim is to understand the frequency of 9 in 728708.

On to step 1:
9 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 9

Advancing to step 2:
The number 9 fits into 72 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 72 from 72 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 9

Step 3:
8 divided by 9 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 9

On to step 4:
87 divided by 9 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 809.0
Subtracting 81 from 87 leaves us with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 9

Going ahead to step 5:
If we divide 60 by 9, we get 6 and a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 8096.0
The remainder is 6 after subtracting 54 from 60.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 9

Step 6:
9 goes into 68 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 80967.0
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.

Let's proceed to step 7:
9 goes into 50 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 80967.5
Deduct 45 from 50 and we're left 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.

Advancing to step 8:
When dividing 50 by 9, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 80967.55
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.

The quotient of the division is 80967.55, and the remainder is 0.005.
