We divide 948545 by 9
The aim is to understand the frequency of 9 in 948545.

Let's proceed to step 1:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 9 away from 9, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 9

Advancing to step 2:
If we divide 4 by 9, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 9

Let's proceed to step 3:
If we divide 48 by 9, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 105.0
The remainder is 3 after subtracting 45 from 48.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 9

Step 4:
9 goes into 35 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 1053.0
Subtracting 27 from 35 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 9

Advancing to step 5:
If we divide 84 by 9, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 10539.0
If we take 81 away from 84, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 9

Going ahead to step 6:
When dividing 35 by 9, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 105393.0
If we subtract 27 from 35, 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.

On to step 7:
The number 9 fits into 80 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 105393.8
If we take 72 away from 80, we end up 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 8:
The number 9 fits into 80 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 105393.88
If we take 72 away from 80, we end up 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.

After the division, we end up with 105393.88 and a remainder of 0.008.
