42953945 divided by 9 
The aim is to understand the frequency of 9 in 42953945.

On to step 1:
9 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 9

Let's proceed to step 2:
42 divided by 9 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 36 from 42 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 9

Advancing to step 3:
9 can be fit into 69 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 47.0
If we subtract 63 from 69, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 9

On to step 4:
9 goes into 65 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 477.0
The remainder is 2 after subtracting 63 from 65.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 9

Step 5:
When dividing 23 by 9, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 4772.0
Deduct 18 from 23 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 9

Advancing to step 6:
9 goes into 59 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 47726.0
Subtract 54 from 59 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 9

Moving on to step 7:
9 goes into 54 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 477266.0
Subtract 54 from 54 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 9

Moving on to step 8:
9 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 4772660.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 9 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4772660.5
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
9 goes into 50 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4772660.55
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 4772660.55 with a balance of 0.005.
