Let's divide 890609 by 23
The aim is to understand the frequency of 23 in 890609.

Step 1:
The number 23 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 23

On to step 2:
The number 23 fits into 89 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 69 from 89 leaves us with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 23

Going ahead to step 3:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 184 from 200 leaves us with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 23

Step 4:
When dividing 166 by 23, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 387.0
The remainder is 5 after subtracting 161 from 166.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 23

Moving on to step 5:
When dividing 50 by 23, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3872.0
Subtracting 46 from 50 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 23

Moving on to step 6:
49 divided by 23 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 38722.0
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:
30 divided by 23 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 38722.1
Deduct 23 from 30 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 8:
When dividing 70 by 23, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 38722.13
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.

Moving on to step 9:
If we divide 10 by 23, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 38722.13
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.

Advancing to step 10:
100 divided by 23 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 38722.1304
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.

Let's proceed to step 11:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 38722.13043
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.

Advancing to step 12:
When dividing 110 by 23, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 38722.130434
If we take 92 away from 110, we end up 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.

On to step 13:
If we divide 180 by 23, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 38722.1304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 14:
190 divided by 23 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 38722.13043478
Deduct 184 from 190 and we're left 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.

The final result is 38722.13043478 with a remainder of 6e-09.
