We divide 690715 by 9
The aim is to understand the frequency of 9 in 690715.

Moving on to step 1:
6 divided by 9 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 9

Step 2:
9 goes into 69 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 63 from 69 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 9

Going ahead to step 3:
9 goes into 60 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtract 54 from 60 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 9

Advancing to step 4:
If we divide 67 by 9, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 767.0
If we subtract 63 from 67, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 9

Going ahead to step 5:
If we divide 41 by 9, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 7674.0
Subtract 36 from 41 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 9

Moving on to step 6:
55 divided by 9 is 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 76746.0
Subtract 54 from 55 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
9 goes into 10 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 76746.1
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
10 divided by 9 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 76746.11
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 76746.11 and a remainder of 0.001.
