Let's divide 312630 by 9
The aim is to understand the frequency of 9 in 312630.

Advancing to step 1:
The number 9 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 9

Let's proceed to step 2:
9 goes into 31 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 27 from 31 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 9

Advancing to step 3:
9 can be fit into 42 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 36 from 42 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 9

Step 4:
If we divide 66 by 9, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 347.0
Subtract 63 from 66 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 9

On to step 5:
33 divided by 9 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3473.0
If we subtract 27 from 33, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 9

Step 6:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 34736.0
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
If we divide 60 by 9, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 34736.6
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 9 fits into 60 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 34736.66
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 34736.66 with a balance of 0.006.
