We divide 235990 by 9
The aim is to understand the frequency of 9 in 235990.

Step 1:
When dividing 2 by 9, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 9

Going ahead to step 2:
9 goes into 23 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 5 after subtracting 18 from 23.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 9

Step 3:
The number 9 fits into 55 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 54 from 55 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 9

Step 4:
9 goes into 19 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 262.0
If we subtract 18 from 19, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 9

Step 5:
9 goes into 19 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2622.0
Subtracting 18 from 19 leaves us with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 9

Moving on to step 6:
10 divided by 9 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 26221.0
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
9 goes into 10 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 26221.1
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
9 can be fit into 10 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 26221.11
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 26221.11 with a balance of 0.001.
