235400 ÷ 23 
The aim is to understand the frequency of 23 in 235400.

On to step 1:
When dividing 2 by 23, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 23

Let's proceed to step 2:
When dividing 23 by 23, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 23 away from 23, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 23

Moving on to step 3:
23 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 5 to get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 23

On to step 4:
23 goes into 54 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtract 46 from 54 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 23

On to step 5:
23 can be fit into 80 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 1023.0
Subtract 69 from 80 to get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 23

Going ahead to step 6:
If we divide 110 by 23, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 10234.0
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 23 is 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 10234.7
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 8:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 10234.78
Deduct 184 from 190 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
When dividing 60 by 23, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 10234.782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
23 can be fit into 140 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 10234.7826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 23, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10234.7826
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
200 divided by 23 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 10234.782608
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
160 divided by 23 is 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 10234.7826086
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
When dividing 220 by 23, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 10234.78260869
If we take 207 away from 220, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 10234.78260869 with a balance of 1.3e-08.
