807588 divided by 23 
The aim is to understand the frequency of 23 in 807588.

On to step 1:
8 divided by 23 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 23

Moving on to step 2:
If we divide 80 by 23, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 69 from 80 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 23

On to step 3:
When dividing 117 by 23, we get 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 115 from 117, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 23

Advancing to step 4:
25 divided by 23 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 351.0
If we subtract 23 from 25, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 23

Going ahead to step 5:
When dividing 28 by 23, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 3511.0
If we take 23 away from 28, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 23

On to step 6:
If we divide 58 by 23, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 35112.0
Subtract 46 from 58 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.

Moving on to step 7:
If we divide 120 by 23, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 35112.5
Subtract 115 from 120 to 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 8:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 35112.52
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.

Going ahead to step 9:
23 goes into 40 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 35112.521
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.

Going ahead to step 10:
When dividing 170 by 23, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 35112.5217
Subtracting 161 from 170 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
23 goes into 90 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 35112.52173
Subtracting 69 from 90 leaves us 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 12:
When dividing 210 by 23, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 35112.521739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
23 goes into 30 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 35112.5217391
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
70 divided by 23 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 35112.52173913
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 35112.52173913 with a balance of 1e-09.
