Let's divide 287430 by 23
The aim is to understand the frequency of 23 in 287430.

Going ahead to step 1:
If we divide 2 by 23, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 23

On to step 2:
23 can be fit into 28 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 23 from 28 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 23

Moving on to step 3:
23 can be fit into 57 2 times, resulting in a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 46 from 57 to get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 23

Let's proceed to step 4:
23 can be fit into 114 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 124.0
Deduct 92 from 114 and we're left with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 23

Going ahead to step 5:
23 can be fit into 223 9 times, resulting in a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 1249.0
If we take 207 away from 223, we end up with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 23

Going ahead to step 6:
160 divided by 23 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 12496.0
Subtracting 138 from 160 leaves us 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.

On to step 7:
The number 23 fits into 220 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 12496.9
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 8:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 12496.95
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
When dividing 150 by 23, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 12496.956
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12496.9565
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
When dividing 50 by 23, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12496.95652
Subtracting 46 from 50 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
If we divide 40 by 23, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 12496.956521
Subtracting 23 from 40 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 12496.9565217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
When dividing 90 by 23, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 12496.95652173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 12496.95652173 with a remaining 2.1e-08.
