We look at the division of 351313 by 9 
The aim is to understand the frequency of 9 in 351313.

On to step 1:
The number 9 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 9

On to step 2:
If we divide 35 by 9, we get 3 and a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 27 from 35 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 9

Going ahead to step 3:
9 goes into 81 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Subtract 81 from 81 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 9

Moving on to step 4:
3 divided by 9 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 390.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 9

Let's proceed to step 5:
The number 9 fits into 31 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 3903.0
Deduct 27 from 31 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 9

On to step 6:
9 can be fit into 43 4 times, resulting in a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 39034.0
If we take 36 away from 43, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
9 goes into 70 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 39034.7
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
9 goes into 70 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 39034.77
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 39034.77 with a balance of 0.007.
