481209 ÷ 23 
The aim is to understand the frequency of 23 in 481209.

Going ahead to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 23

On to step 2:
23 can be fit into 48 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 46 from 48 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 23

Advancing to step 3:
23 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 21, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 23

Going ahead to step 4:
When dividing 212 by 23, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 209.0
Subtracting 207 from 212 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 23

Let's proceed to step 5:
If we divide 50 by 23, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 2092.0
Subtract 46 from 50 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 23

Let's proceed to step 6:
The number 23 fits into 49 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 20922.0
The remainder is 3 after subtracting 46 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 23, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 20922.1
If we subtract 23 from 30, we 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.

Going ahead to step 8:
23 goes into 70 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 20922.13
The remainder is 1 after subtracting 69 from 70.
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 9:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 20922.13
Subtract 0 from 10 to 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 10:
23 can be fit into 100 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 20922.1304
Deduct 92 from 100 and we're left 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.

Moving on to step 11:
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: 20922.13043
Deduct 69 from 80 and we're left 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.

Step 12:
110 divided by 23 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 20922.130434
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.

Moving on to step 13:
When dividing 180 by 23, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 20922.1304347
If we take 161 away from 180, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
23 goes into 190 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 20922.13043478
Subtracting 184 from 190 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 20922.13043478 with a remaining 6e-09.
