We look at the division of 783517 by 9 
The aim is to understand the frequency of 9 in 783517.

Moving on to step 1:
7 divided by 9 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 9

Step 2:
When dividing 78 by 9, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 72 away from 78, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 9

Going ahead to step 3:
When dividing 63 by 9, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 63 from 63 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 9

Step 4:
5 divided by 9 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 870.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 9

Advancing to step 5:
The number 9 fits into 51 5 times, leaving a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 8705.0
The remainder is 6 after subtracting 45 from 51.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 9

Let's proceed to step 6:
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: 87057.0
Deduct 63 from 67 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 9 fits into 40 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 87057.4
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 9, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 87057.44
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 87057.44 with a balance of 0.004.
