790322 ÷ 9 
The aim is to understand the frequency of 9 in 790322.

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
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 9

Let's proceed to step 2:
9 can be fit into 79 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 72 from 79, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 9

Moving on to step 3:
70 divided by 9 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 63 from 70 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 9

Step 4:
9 goes into 73 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 878.0
The remainder is 1 after subtracting 72 from 73.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 9

On to step 5:
If we divide 12 by 9, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 8781.0
If we take 9 away from 12, we end up with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 9

On to step 6:
9 goes into 32 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 87813.0
Subtracting 27 from 32 leaves us 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.

On to step 7:
50 divided by 9 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 87813.5
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.

Let's proceed to step 8:
50 divided by 9 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 87813.55
If we subtract 45 from 50, we 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 final outcome is 87813.55, with a leftover of 0.005.
