We're dividing 993893 by 23 
The aim is to understand the frequency of 23 in 993893.

On to step 1:
23 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 23

Step 2:
23 goes into 99 4 times with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 92 from 99 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 23

Let's proceed to step 3:
23 can be fit into 73 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 69 from 73, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 23

Going ahead to step 4:
If we divide 48 by 23, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 432.0
Deduct 46 from 48 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 23

Let's proceed to step 5:
If we divide 29 by 23, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 4321.0
If we take 23 away from 29, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 23

Step 6:
The number 23 fits into 63 2 times, leaving a remainder of 17.
The next digit of our result is 2. 
Result so far: 43212.0
Deduct 46 from 63 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 43212.7
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 43212.73
If we take 69 away from 90, we end up 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 9:
If we divide 210 by 23, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 43212.739
If we take 207 away from 210, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
If we divide 30 by 23, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 43212.7391
The remainder is 7 after subtracting 23 from 30.
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 11:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 43212.73913
If we subtract 69 from 70, we 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.

Advancing to step 12:
10 divided by 23 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 43212.73913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 23, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 43212.7391304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
80 divided by 23 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 43212.73913043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 43212.73913043 with a remainder of 1.1e-08.
