863533 divided by 23 
The aim is to understand the frequency of 23 in 863533.

Going ahead to step 1:
When dividing 8 by 23, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 23

On to step 2:
86 divided by 23 is 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 69 from 86 and we're left with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 23

Moving on to step 3:
When dividing 173 by 23, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Deduct 161 from 173 and we're left with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 23

Moving on to step 4:
When dividing 125 by 23, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
Subtract 115 from 125 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 23

Moving on to step 5:
If we divide 103 by 23, we get 4 and a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 3754.0
Subtracting 92 from 103 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 23

Let's proceed to step 6:
23 can be fit into 113 4 times, resulting in a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 37544.0
Deduct 92 from 113 and we're left 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.

On to step 7:
When dividing 210 by 23, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 37544.9
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.

Going ahead to step 8:
30 divided by 23 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 37544.91
Subtracting 23 from 30 leaves us 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 9:
70 divided by 23 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 37544.913
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.

On to step 10:
The number 23 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 37544.913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 23, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 37544.91304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
If we divide 80 by 23, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 37544.913043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
When dividing 110 by 23, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 37544.9130434
If we take 92 away from 110, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
23 can be fit into 180 7 times, resulting in a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 37544.91304347
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 37544.91304347, with a leftover of 1.9e-08.
