We're dividing 99643 by 9 
The aim is to understand the frequency of 9 in 99643.

Moving on to step 1:
9 can be fit into 9 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 9 from 9 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 9

Step 2:
When dividing 9 by 9, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 9 from 9 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 9

Step 3:
9 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 9

Step 4:
64 divided by 9 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 1107.0
If we take 63 away from 64, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 9

Going ahead to step 5:
9 goes into 13 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 11071.0
If we subtract 9 from 13, 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.

Advancing to step 6:
9 can be fit into 40 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 11071.4
Subtracting 36 from 40 leaves us 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.

Advancing to step 7:
If we divide 40 by 9, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 11071.44
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.

In conclusion, the division gives 11071.44 with a balance of 0.004.
