We're dividing 574979 by 23 
The aim is to understand the frequency of 23 in 574979.

Advancing to step 1:
When dividing 5 by 23, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 23

Step 2:
23 goes into 57 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 46 away from 57, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 23

Advancing to step 3:
114 divided by 23 is 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we take 92 away from 114, we end up with 22.
Fetch the next digit (9) from the dividend, attach it to 22 and continue: 229 / 23

Advancing to step 4:
23 can be fit into 229 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 249.0
Subtracting 207 from 229 leaves us with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 23

Step 5:
When dividing 227 by 23, we get 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 2499.0
If we subtract 207 from 227, we get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 23

Let's proceed to step 6:
23 can be fit into 209 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 24999.0
The remainder is 2 after subtracting 207 from 209.
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:
23 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 24999.0
If we subtract 0 from 20, we 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.

On to step 8:
If we divide 200 by 23, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 24999.08
If we take 184 away from 200, we end up 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.

On to step 9:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 24999.086
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
23 goes into 220 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 24999.0869
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.

Step 11:
130 divided by 23 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 24999.08695
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.

Moving on to step 12:
If we divide 150 by 23, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 24999.086956
If we take 138 away from 150, we end up 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.

Let's proceed to step 13:
120 divided by 23 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 24999.0869565
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.

On to step 14:
If we divide 50 by 23, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 24999.08695652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 24999.08695652 with a remainder of 4e-09.
