We're dividing 663629 by 23 
The aim is to understand the frequency of 23 in 663629.

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
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 23

Going ahead to step 2:
23 goes into 66 2 times with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 20 after subtracting 46 from 66.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 23

Moving on to step 3:
203 divided by 23 is 8 with a remainder of 19.
The next digit of our result is 8. 
Result so far: 28.0
If we take 184 away from 203, we end up with 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 23

Going ahead to step 4:
23 goes into 196 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 288.0
The remainder is 12 after subtracting 184 from 196.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 23

Advancing to step 5:
If we divide 122 by 23, we get 5 and a remainder of 7.
The next digit of our result is 5. 
Result so far: 2885.0
If we take 115 away from 122, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 23

Let's proceed to step 6:
79 divided by 23 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 28853.0
Subtracting 69 from 79 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 28853.4
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
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: 28853.43
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
If we divide 110 by 23, we get 4 and a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 28853.434
Subtracting 92 from 110 leaves us 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.

Going ahead to step 10:
When dividing 180 by 23, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 28853.4347
If we take 161 away from 180, we end up 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.

Moving on to step 11:
The number 23 fits into 190 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 28853.43478
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.

Step 12:
23 can be fit into 60 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 28853.434782
Subtracting 46 from 60 leaves us 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.

Advancing to step 13:
If we divide 140 by 23, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 28853.4347826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
20 divided by 23 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 28853.4347826
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.

The quotient of the division is 28853.4347826, and the remainder is 2e-08.
