Let's divide 730118 by 9
The aim is to understand the frequency of 9 in 730118.

On to step 1:
7 divided by 9 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 9

Step 2:
9 goes into 73 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 1 after subtracting 72 from 73.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 9

On to step 3:
10 divided by 9 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
The remainder is 1 after subtracting 9 from 10.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 9

Step 4:
The number 9 fits into 11 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 811.0
If we subtract 9 from 11, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 9

On to step 5:
The number 9 fits into 21 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 8112.0
If we take 18 away from 21, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 9

Moving on to step 6:
9 can be fit into 38 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 81124.0
If we subtract 36 from 38, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 81124.2
Deduct 18 from 20 and we're left 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 8:
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: 81124.22
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 81124.22 and a remainder of 0.002.
