626580 divided by 23 
The aim is to understand the frequency of 23 in 626580.

Going ahead to step 1:
6 divided by 23 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 23

Going ahead to step 2:
When dividing 62 by 23, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 46 away from 62, we end up with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 23

Advancing to step 3:
The number 23 fits into 166 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 161 away from 166, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 23

On to step 4:
The number 23 fits into 55 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 272.0
The remainder is 9 after subtracting 46 from 55.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 23

Step 5:
When dividing 98 by 23, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 2724.0
If we subtract 92 from 98, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 23

Moving on to step 6:
60 divided by 23 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 27242.0
If we take 46 away from 60, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 27242.6
Subtracting 138 from 140 leaves us with 2.
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 8:
20 divided by 23 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 27242.6
The remainder is 20 after subtracting 0 from 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 9:
200 divided by 23 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 27242.608
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.

Going ahead to step 10:
23 goes into 160 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 27242.6086
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 11:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 27242.60869
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.

Let's proceed to step 12:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 27242.608695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
150 divided by 23 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 27242.6086956
The remainder is 12 after subtracting 138 from 150.
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 14:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 27242.60869565
If we subtract 115 from 120, we 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.

Our division results in 27242.60869565 with a remaining 5e-09.
