We're dividing 730603 by 9 
The aim is to understand the frequency of 9 in 730603.

Let's proceed to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 9

Let's proceed to step 2:
9 goes into 73 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 72 from 73 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 9

On to step 3:
9 can be fit into 10 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 9 away from 10, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 9

Let's proceed to step 4:
The number 9 fits into 16 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 811.0
Subtracting 9 from 16 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 9

Let's proceed to step 5:
9 goes into 70 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 8117.0
If we subtract 63 from 70, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 9

Advancing to step 6:
9 goes into 73 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 81178.0
Subtracting 72 from 73 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 9 fits into 10 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 81178.1
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
9 can be fit into 10 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 81178.11
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 81178.11 with a balance of 0.001.
