522903 ÷ 23 
The aim is to understand the frequency of 23 in 522903.

Moving on to step 1:
23 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 23

Let's proceed to step 2:
When dividing 52 by 23, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 46 away from 52, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 23

Moving on to step 3:
When dividing 62 by 23, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 16 after subtracting 46 from 62.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 23

On to step 4:
The number 23 fits into 169 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 227.0
Deduct 161 from 169 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 23

Going ahead to step 5:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 2273.0
Deduct 69 from 80 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 23

On to step 6:
23 goes into 113 4 times with a remainder of 21.
Write down 4 as next digit of the result. 
Result so far: 22734.0
Subtract 92 from 113 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.

Advancing to step 7:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 22734.9
If we take 207 away from 210, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 22734.91
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.

Moving on to step 9:
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: 22734.913
Subtracting 69 from 70 leaves us 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.

Advancing to step 10:
The number 23 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 22734.913
If we subtract 0 from 10, we get 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 11:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 22734.91304
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.

Advancing to step 12:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 22734.913043
Subtracting 69 from 80 leaves us 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.

Advancing to step 13:
110 divided by 23 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 22734.9130434
If we subtract 92 from 110, 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.

On to step 14:
180 divided by 23 is 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 22734.91304347
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 22734.91304347 and a remainder of 1.9e-08.
