We look at the division of 753948 by 9 
The aim is to understand the frequency of 9 in 753948.

Moving on to step 1:
The number 9 fits into 7 0 times, leaving 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.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 9

Step 2:
The number 9 fits into 75 8 times, leaving a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 72 from 75 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 9

Going ahead to step 3:
When dividing 33 by 9, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 27 from 33 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 9

Advancing to step 4:
When dividing 69 by 9, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 837.0
If we take 63 away from 69, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 9

Step 5:
The number 9 fits into 64 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 8377.0
The remainder is 1 after subtracting 63 from 64.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 9

Step 6:
18 divided by 9 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 83772.0
Subtract 18 from 18 to 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.

Moving on to step 7:
If we divide 0 by 9, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 83772.0
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.

Let's proceed to step 8:
When dividing 0 by 9, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 83772.0
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.

After the division, we end up with 83772.0 and a remainder of 0.0.
