623693 divided by 23 
The aim is to understand the frequency of 23 in 623693.

Let's proceed to step 1:
23 can be fit into 6 0 times, resulting in 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.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 23

Going ahead to step 2:
The number 23 fits into 62 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 46 away from 62, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 23

Advancing to step 3:
The number 23 fits into 163 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 161 from 163, we get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 23

On to step 4:
23 goes into 26 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 271.0
Deduct 23 from 26 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 23

Going ahead to step 5:
When dividing 39 by 23, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 2711.0
Subtracting 23 from 39 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 23

On to step 6:
If we divide 163 by 23, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 27117.0
Deduct 161 from 163 and we're left 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.

On to step 7:
When dividing 20 by 23, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 27117.0
Deduct 0 from 20 and we're left with 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 8:
If we divide 200 by 23, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 27117.08
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:
160 divided by 23 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 27117.086
If we take 138 away from 160, we end up 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.

Step 10:
If we divide 220 by 23, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 27117.0869
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.

Step 11:
If we divide 130 by 23, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 27117.08695
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.

Step 12:
150 divided by 23 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 27117.086956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 27117.0869565
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.

Moving on to step 14:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 27117.08695652
If we subtract 46 from 50, we 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.

Our division results in 27117.08695652 with a remaining 4e-09.
