523397 ÷ 23 
The aim is to understand the frequency of 23 in 523397.

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
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 23

On to step 2:
If we divide 52 by 23, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 46 away from 52, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 23

Going ahead to step 3:
23 goes into 63 2 times with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 17 after subtracting 46 from 63.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 23

Going ahead to step 4:
23 can be fit into 173 7 times, resulting in a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
Deduct 161 from 173 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 23

On to step 5:
If we divide 129 by 23, we get 5 and a remainder of 14.
The next digit of our result is 5. 
Result so far: 2275.0
If we take 115 away from 129, we end up with 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 23

Moving on to step 6:
If we divide 147 by 23, we get 6 and a remainder of 9.
The next digit of our result is 6. 
Result so far: 22756.0
If we take 138 away from 147, we end up 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.

Advancing to step 7:
If we divide 90 by 23, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 22756.3
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 22756.39
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.

On to step 9:
23 can be fit into 30 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 22756.391
The remainder is 7 after subtracting 23 from 30.
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 10:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 22756.3913
If we subtract 69 from 70, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
10 divided by 23 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 22756.3913
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.

Let's proceed to step 12:
23 can be fit into 100 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 22756.391304
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.

Advancing to step 13:
When dividing 80 by 23, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 22756.3913043
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.

Advancing to step 14:
If we divide 110 by 23, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 22756.39130434
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.

After the division, we end up with 22756.39130434 and a remainder of 1.8e-08.
