275166 ÷ 23 
The aim is to understand the frequency of 23 in 275166.

Advancing to step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 23

Step 2:
23 can be fit into 27 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 23 from 27 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 23

Let's proceed to step 3:
23 goes into 45 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 23 from 45 leaves us with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 23

On to step 4:
If we divide 221 by 23, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we take 207 away from 221, we end up with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 23

On to step 5:
146 divided by 23 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1196.0
If we take 138 away from 146, we end up with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 23

Moving on to step 6:
23 can be fit into 86 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 11963.0
Deduct 69 from 86 and we're left 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.

On to step 7:
When dividing 170 by 23, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 11963.7
The remainder is 9 after subtracting 161 from 170.
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 8:
If we divide 90 by 23, we get 3 and a remainder of 21.
The next digit of our result is 3. 
Result so far: 11963.73
If we subtract 69 from 90, we 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 9:
23 goes into 210 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 11963.739
Deduct 207 from 210 and we're left 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 10:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 11963.7391
Deduct 23 from 30 and we're left 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.

On to step 11:
70 divided by 23 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 11963.73913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 12:
10 divided by 23 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 11963.73913
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
100 divided by 23 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 11963.7391304
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
80 divided by 23 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 11963.73913043
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 11963.73913043 with a remaining 1.1e-08.
