153568 divided by 23 
The aim is to understand the frequency of 23 in 153568.

Going ahead to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 23

Going ahead to step 2:
If we divide 15 by 23, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 23

Step 3:
23 can be fit into 153 6 times, resulting in a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 15 after subtracting 138 from 153.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 23

Step 4:
The number 23 fits into 155 6 times, leaving a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 138 from 155 to get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 23

Going ahead to step 5:
23 can be fit into 176 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 667.0
Subtracting 161 from 176 leaves us with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 23

On to step 6:
The number 23 fits into 158 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 6676.0
Subtract 138 from 158 to 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.

On to step 7:
23 goes into 200 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 6676.8
If we subtract 184 from 200, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
23 goes into 160 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6676.86
If we take 138 away from 160, we end up 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 9:
23 goes into 220 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 6676.869
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
23 can be fit into 130 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 6676.8695
Subtracting 115 from 130 leaves us 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 11:
If we divide 150 by 23, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6676.86956
Deduct 138 from 150 and we're left 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.

On to step 12:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6676.869565
If we take 115 away from 120, we end up 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.

Let's proceed to step 13:
50 divided by 23 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6676.8695652
If we subtract 46 from 50, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
When dividing 40 by 23, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 6676.86956521
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.

Our division results in 6676.86956521 with a remaining 1.7e-08.
