We divide 9399 by 23
The aim is to understand the frequency of 23 in 9399.

Advancing to step 1:
If we divide 9 by 23, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 23

Moving on to step 2:
If we divide 93 by 23, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 92 from 93 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 23

Let's proceed to step 3:
If we divide 19 by 23, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 19 to get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 23

Advancing to step 4:
The number 23 fits into 199 8 times, leaving a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 408.0
If we subtract 184 from 199, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 5:
150 divided by 23 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 408.6
If we take 138 away from 150, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 6:
When dividing 120 by 23, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 408.65
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 408.652
If we take 46 away from 50, 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.

Going ahead to step 8:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 408.6521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 408.65217
Deduct 161 from 170 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
90 divided by 23 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 408.652173
Subtracting 69 from 90 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
If we divide 210 by 23, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 408.6521739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
If we divide 30 by 23, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 408.65217391
Subtracting 23 from 30 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.

In conclusion, the division gives 408.65217391 with a balance of 7e-09.
