127886 divided by 23 
The aim is to understand the frequency of 23 in 127886.

On to step 1:
The number 23 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 23

On to step 2:
23 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 23

Step 3:
The number 23 fits into 127 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 115 from 127, we get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 23

Let's proceed to step 4:
If we divide 128 by 23, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 13 after subtracting 115 from 128.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 23

Moving on to step 5:
138 divided by 23 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 556.0
If we take 138 away from 138, we end up with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 23

Advancing to step 6:
6 divided by 23 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 5560.0
If we take 0 away from 6, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
When dividing 60 by 23, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 5560.2
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
The number 23 fits into 140 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 5560.26
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 5560.26
Subtract 0 from 20 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.

Let's proceed to step 10:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 5560.2608
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 5560.26086
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.

Advancing to step 12:
When dividing 220 by 23, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 5560.260869
Deduct 207 from 220 and we're left 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 13:
If we divide 130 by 23, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5560.2608695
The remainder is 15 after subtracting 115 from 130.
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 14:
The number 23 fits into 150 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 5560.26086956
Subtracting 138 from 150 leaves us 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.

The final result is 5560.26086956 with a remainder of 1.2e-08.
