510571 divided by 23 
The aim is to understand the frequency of 23 in 510571.

Advancing to step 1:
The number 23 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 23

Moving on to step 2:
When dividing 51 by 23, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 46 away from 51, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 23

Let's proceed to step 3:
50 divided by 23 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 46 from 50, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 23

Advancing to step 4:
The number 23 fits into 45 1 times, leaving a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
Subtract 23 from 45 to get 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 23

Step 5:
227 divided by 23 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 2219.0
Subtract 207 from 227 to get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 23

Moving on to step 6:
201 divided by 23 is 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 22198.0
If we take 184 away from 201, we end up 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.

Going ahead to step 7:
23 goes into 170 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 22198.7
Subtracting 161 from 170 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
23 goes into 90 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 22198.73
If we subtract 69 from 90, we 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.

Going ahead to step 9:
When dividing 210 by 23, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 22198.739
Subtract 207 from 210 to get 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 10:
If we divide 30 by 23, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 22198.7391
Subtract 23 from 30 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
When dividing 70 by 23, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 22198.73913
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
10 divided by 23 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 22198.73913
Subtracting 0 from 10 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.

Step 13:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 22198.7391304
If we subtract 92 from 100, we get 8.
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 14:
When dividing 80 by 23, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 22198.73913043
Subtract 69 from 80 to 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.

The quotient of the division is 22198.73913043, and the remainder is 1.1e-08.
