Let's divide 668865 by 23
The aim is to understand the frequency of 23 in 668865.

Advancing to step 1:
When dividing 6 by 23, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 23

Going ahead to step 2:
23 can be fit into 66 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 20 after subtracting 46 from 66.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 23

Let's proceed to step 3:
23 goes into 208 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtract 207 from 208 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 23

Advancing to step 4:
When dividing 18 by 23, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 290.0
The remainder is 18 after subtracting 0 from 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 23

Going ahead to step 5:
23 goes into 186 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2908.0
If we subtract 184 from 186, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 23

Step 6:
23 goes into 25 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 29081.0
Deduct 23 from 25 and we're left 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.

Going ahead to step 7:
20 divided by 23 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 29081.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
23 goes into 200 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 29081.08
Subtract 184 from 200 to 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.

Let's proceed to step 9:
160 divided by 23 is 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 29081.086
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.

Let's proceed to step 10:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 29081.0869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 29081.08695
Subtract 115 from 130 to 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 12:
If we divide 150 by 23, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 29081.086956
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.

Moving on to step 13:
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: 29081.0869565
Subtracting 115 from 120 leaves us 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.

Advancing to step 14:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 29081.08695652
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.

After the division, we end up with 29081.08695652 and a remainder of 4e-09.
