We divide 503541 by 23
The aim is to understand the frequency of 23 in 503541.

Advancing to step 1:
23 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 23

Moving on to step 2:
If we divide 50 by 23, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 46 from 50, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 23

Moving on to step 3:
43 divided by 23 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 23 from 43 and we're left with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 23

Going ahead to step 4:
205 divided by 23 is 8 with a remainder of 21.
The next digit of our result is 8. 
Result so far: 218.0
Subtracting 184 from 205 leaves us with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 23

Advancing to step 5:
If we divide 214 by 23, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2189.0
The remainder is 7 after subtracting 207 from 214.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 23

Going ahead to step 6:
When dividing 71 by 23, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 21893.0
The remainder is 2 after subtracting 69 from 71.
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 7:
If we divide 20 by 23, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 21893.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
23 can be fit into 200 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 21893.08
If we take 184 away from 200, we end up 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.

Going ahead to step 9:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 21893.086
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.

Advancing to step 10:
23 goes into 220 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 21893.0869
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.

Step 11:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 21893.08695
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
150 divided by 23 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 21893.086956
Deduct 138 from 150 and we're left 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.

Advancing to step 13:
23 goes into 120 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 21893.0869565
If we take 115 away from 120, we end up 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.

Step 14:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 21893.08695652
Deduct 46 from 50 and we're left 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.

Our division results in 21893.08695652 with a remaining 4e-09.
