Let's divide 636819 by 23
The aim is to understand the frequency of 23 in 636819.

Moving on to step 1:
When dividing 6 by 23, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 23

Step 2:
23 can be fit into 63 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 17 after subtracting 46 from 63.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 23

Advancing to step 3:
When dividing 176 by 23, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 161 from 176 to get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 23

Advancing to step 4:
158 divided by 23 is 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 276.0
Subtract 138 from 158 to get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 23

Advancing to step 5:
The number 23 fits into 201 8 times, leaving a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 2768.0
Subtract 184 from 201 to get 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 23

Moving on to step 6:
When dividing 179 by 23, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 27687.0
If we subtract 161 from 179, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
If we divide 180 by 23, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 27687.7
Deduct 161 from 180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
190 divided by 23 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 27687.78
Deduct 184 from 190 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
23 can be fit into 60 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 27687.782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
140 divided by 23 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 27687.7826
If we take 138 away from 140, we end up 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.

Advancing to step 11:
20 divided by 23 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 27687.7826
Subtracting 0 from 20 leaves us 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.

Going ahead to step 12:
23 can be fit into 200 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 27687.782608
Subtracting 184 from 200 leaves us 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.

Moving on to step 13:
23 can be fit into 160 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 27687.7826086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
When dividing 220 by 23, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 27687.78260869
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.

The final result is 27687.78260869 with a remainder of 1.3e-08.
