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

Step 1:
When dividing 5 by 23, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 23

Step 2:
56 divided by 23 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 46 away from 56, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 23

Going ahead to step 3:
23 goes into 104 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 92 from 104 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 23

Going ahead to step 4:
125 divided by 23 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 245.0
Subtract 115 from 125 to get 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 23

On to step 5:
23 can be fit into 107 4 times, resulting in a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 2454.0
Subtract 92 from 107 to get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 23

Let's proceed to step 6:
When dividing 158 by 23, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 24546.0
The remainder is 20 after subtracting 138 from 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 24546.8
Subtracting 184 from 200 leaves us 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.

Moving on to step 8:
23 can be fit into 160 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 24546.86
Subtracting 138 from 160 leaves us 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.

Moving on to step 9:
220 divided by 23 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 24546.869
If we take 207 away from 220, we end up 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:
130 divided by 23 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 24546.8695
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 11:
If we divide 150 by 23, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 24546.86956
Deduct 138 from 150 and we're left 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.

On to step 12:
23 goes into 120 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 24546.869565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 24546.8695652
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.

Step 14:
23 goes into 40 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
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 quotient of the division is 24546.86956521, and the remainder is 1.7e-08.
