We look at the division of 941749 by 9 
The aim is to understand the frequency of 9 in 941749.

Let's proceed to step 1:
If we divide 9 by 9, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 9

On to step 2:
If we divide 4 by 9, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 4, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 9

Let's proceed to step 3:
When dividing 41 by 9, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 36 from 41 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 9

Advancing to step 4:
9 can be fit into 57 6 times, resulting in a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 1046.0
The remainder is 3 after subtracting 54 from 57.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 9

Step 5:
9 goes into 34 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 10463.0
The remainder is 7 after subtracting 27 from 34.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 9

On to step 6:
79 divided by 9 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 104638.0
If we take 72 away from 79, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 9 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 104638.7
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
If we divide 70 by 9, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 104638.77
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 104638.77 with a remainder of 0.007.
