We're dividing 624270 by 9 
The aim is to understand the frequency of 9 in 624270.

Let's proceed to step 1:
9 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 9

Going ahead to step 2:
9 can be fit into 62 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 54 from 62 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 9

Let's proceed to step 3:
84 divided by 9 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we subtract 81 from 84, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 9

Moving on to step 4:
If we divide 32 by 9, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 693.0
Subtracting 27 from 32 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 9

Moving on to step 5:
If we divide 57 by 9, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6936.0
If we take 54 away from 57, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 9

On to step 6:
The number 9 fits into 30 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 69363.0
The remainder is 3 after subtracting 27 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 9 fits into 30 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 69363.3
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 69363.33
If we take 27 away from 30, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 69363.33 with a balance of 0.003.
