We're dividing 747945 by 9 
The aim is to understand the frequency of 9 in 747945.

Step 1:
When dividing 7 by 9, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 9

Let's proceed to step 2:
9 can be fit into 74 8 times, resulting in a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 72 from 74 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 9

Going ahead to step 3:
The number 9 fits into 27 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Deduct 27 from 27 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 9

Step 4:
When dividing 9 by 9, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 831.0
Subtracting 9 from 9 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 9

Advancing to step 5:
9 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 8310.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 9

On to step 6:
If we divide 45 by 9, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 83105.0
If we take 45 away from 45, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
If we divide 0 by 9, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 83105.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 83105.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 83105.0 with a remaining 0.0.
