We look at the division of 53942705 by 9 
The aim is to understand the frequency of 9 in 53942705.

Let's proceed to step 1:
If we divide 5 by 9, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 9

Moving on to step 2:
The number 9 fits into 53 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 45 from 53, we get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 9

Step 3:
9 goes into 89 9 times with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we subtract 81 from 89, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 9

Moving on to step 4:
When dividing 84 by 9, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 599.0
Subtracting 81 from 84 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 9

On to step 5:
32 divided by 9 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 5993.0
Deduct 27 from 32 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 9

Let's proceed to step 6:
When dividing 57 by 9, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 59936.0
Subtract 54 from 57 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 9

Step 7:
If we divide 30 by 9, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 599363.0
Deduct 27 from 30 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 9

Going ahead to step 8:
The number 9 fits into 35 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 5993633.0
Subtracting 27 from 35 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
9 goes into 80 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 5993633.8
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 9, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 5993633.88
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 5993633.88 with a remainder of 0.008.
