564578 ÷ 23 
The aim is to understand the frequency of 23 in 564578.

Advancing to step 1:
23 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 23

Let's proceed to step 2:
If we divide 56 by 23, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 10 after subtracting 46 from 56.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 23

Going ahead to step 3:
23 can be fit into 104 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 12 after subtracting 92 from 104.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 23

Moving on to step 4:
23 goes into 125 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 245.0
If we take 115 away from 125, we end up with 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 23

Step 5:
23 goes into 107 4 times with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 2454.0
If we subtract 92 from 107, we get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 23

Advancing to step 6:
158 divided by 23 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 24546.0
If we subtract 138 from 158, 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.

Let's proceed to step 7:
23 goes into 200 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 24546.8
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.

On to step 8:
23 goes into 160 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 24546.86
If we subtract 138 from 160, we 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.

Moving on to step 9:
If we divide 220 by 23, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 24546.869
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.

Let's proceed to step 10:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 24546.8695
If we take 115 away from 130, we end up 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 11:
When dividing 150 by 23, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 24546.86956
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.

Step 12:
If we divide 120 by 23, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 24546.869565
Subtracting 115 from 120 leaves us 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 13:
23 can be fit into 50 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 24546.8695652
Subtract 46 from 50 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
23 goes into 40 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 24546.86956521
If we take 23 away from 40, we end up 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.

The final outcome is 24546.86956521, with a leftover of 1.7e-08.
