We look at the division of 667465 by 23 
The aim is to understand the frequency of 23 in 667465.

Step 1:
23 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 23

Step 2:
66 divided by 23 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 46 from 66, we get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 23

Advancing to step 3:
23 goes into 207 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 207 from 207 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 23

Step 4:
23 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 290.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 23

Moving on to step 5:
The number 23 fits into 46 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2902.0
If we subtract 46 from 46, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 23

Advancing to step 6:
If we divide 5 by 23, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 29020.0
Deduct 0 from 5 and we're left 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.

On to step 7:
23 goes into 50 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 29020.2
Deduct 46 from 50 and we're left 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.

On to step 8:
When dividing 40 by 23, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 29020.21
Subtracting 23 from 40 leaves us 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.

Advancing to step 9:
23 goes into 170 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 29020.217
Subtracting 161 from 170 leaves us 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.

On to step 10:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 29020.2173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
23 goes into 210 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 29020.21739
Subtracting 207 from 210 leaves us 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.

Step 12:
When dividing 30 by 23, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 29020.217391
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
70 divided by 23 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 29020.2173913
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 29020.2173913
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 29020.2173913 and a remainder of 1e-08.
