We look at the division of 954643 by 9 
The aim is to understand the frequency of 9 in 954643.

Going ahead to step 1:
When dividing 9 by 9, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 9

Going ahead to step 2:
The number 9 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 9

Step 3:
9 can be fit into 54 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtracting 54 from 54 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 9

Moving on to step 4:
6 divided by 9 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 1060.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 9

On to step 5:
9 goes into 64 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 10607.0
Subtracting 63 from 64 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 9

Going ahead to step 6:
The number 9 fits into 13 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 106071.0
Subtract 9 from 13 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 9, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 106071.4
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
9 goes into 40 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 106071.44
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 106071.44, and the remainder is 0.004.
