We divide 249980 by 23
The aim is to understand the frequency of 23 in 249980.

Moving on to step 1:
If we divide 2 by 23, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 23

Moving on to step 2:
23 can be fit into 24 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 23 away from 24, we end up with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 23

Let's proceed to step 3:
The number 23 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 19 to get 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 23

Going ahead to step 4:
If we divide 199 by 23, we get 8 and a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 184 away from 199, we end up with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 23

Advancing to step 5:
If we divide 158 by 23, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 1086.0
If we take 138 away from 158, we end up with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 23

Going ahead to step 6:
If we divide 200 by 23, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 10868.0
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.

Advancing to step 7:
23 goes into 160 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 10868.6
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.

On to step 8:
220 divided by 23 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 10868.69
If we subtract 207 from 220, we 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.

On to step 9:
23 goes into 130 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10868.695
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.

Going ahead to step 10:
150 divided by 23 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 10868.6956
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.

Step 11:
120 divided by 23 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 10868.69565
Subtract 115 from 120 to get 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 12:
23 goes into 50 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10868.695652
Subtracting 46 from 50 leaves us 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.

Moving on to step 13:
If we divide 40 by 23, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 10868.6956521
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.

Let's proceed to step 14:
23 goes into 170 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 10868.69565217
If we take 161 away from 170, we end up 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.

The final outcome is 10868.69565217, with a leftover of 9e-09.
