353825 divided by 23 
The aim is to understand the frequency of 23 in 353825.

Let's proceed to step 1:
When dividing 3 by 23, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 23

Step 2:
23 can be fit into 35 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 23 from 35 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 23

Moving on to step 3:
23 can be fit into 123 5 times, resulting in a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 115 from 123 to get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 23

Moving on to step 4:
23 goes into 88 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 153.0
If we subtract 69 from 88, we get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 23

Going ahead to step 5:
The number 23 fits into 192 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 1538.0
The remainder is 8 after subtracting 184 from 192.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 23

Let's proceed to step 6:
If we divide 85 by 23, we get 3 and a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 15383.0
The remainder is 16 after subtracting 69 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
When dividing 160 by 23, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 15383.6
Subtracting 138 from 160 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
If we divide 220 by 23, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 15383.69
Subtracting 207 from 220 leaves us 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.

On to step 9:
23 can be fit into 130 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15383.695
If we take 115 away from 130, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
The number 23 fits into 150 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 15383.6956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
If we divide 120 by 23, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15383.69565
If we subtract 115 from 120, we get 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 12:
50 divided by 23 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 15383.695652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
40 divided by 23 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 15383.6956521
Subtract 23 from 40 to get 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 14:
If we divide 170 by 23, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 15383.69565217
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.

The final result is 15383.69565217 with a remainder of 9e-09.
