580869 divided by 23 
The aim is to understand the frequency of 23 in 580869.

Let's proceed to step 1:
23 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 23

Let's proceed to step 2:
If we divide 58 by 23, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 46 away from 58, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 23

On to step 3:
23 goes into 120 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 115 from 120 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 23

Let's proceed to step 4:
23 can be fit into 58 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
If we take 46 away from 58, we end up with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 23

Going ahead to step 5:
If we divide 126 by 23, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 2525.0
Subtracting 115 from 126 leaves us with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 23

Advancing to step 6:
The number 23 fits into 119 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 25255.0
If we take 115 away from 119, we end up 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 7:
When dividing 40 by 23, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 25255.1
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 25255.17
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 25255.173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 25255.1739
If we subtract 207 from 210, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
If we divide 30 by 23, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 25255.17391
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 25255.173913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
23 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 25255.173913
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
23 can be fit into 100 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 25255.17391304
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 25255.17391304 and a remainder of 8e-09.
