We're dividing 89581057 by 23 
The aim is to understand the frequency of 23 in 89581057.

Moving on to step 1:
When dividing 8 by 23, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 23

Advancing to step 2:
The number 23 fits into 89 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 69 from 89 leaves us with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 23

Let's proceed to step 3:
The number 23 fits into 205 8 times, leaving a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Deduct 184 from 205 and we're left with 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 23

On to step 4:
218 divided by 23 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 389.0
The remainder is 11 after subtracting 207 from 218.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 23

Let's proceed to step 5:
The number 23 fits into 111 4 times, leaving a remainder of 19.
The next digit of our result is 4. 
Result so far: 3894.0
If we take 92 away from 111, we end up with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 23

Step 6:
23 can be fit into 190 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 38948.0
If we subtract 184 from 190, we get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 23

Step 7:
23 goes into 65 2 times with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 389482.0
Subtract 46 from 65 to get 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 23

Moving on to step 8:
23 can be fit into 197 8 times, resulting in a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 3894828.0
The remainder is 13 after subtracting 184 from 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
The number 23 fits into 130 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3894828.5
Deduct 115 from 130 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
23 goes into 150 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3894828.56
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
23 goes into 120 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3894828.565
If we take 115 away from 120, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
If we divide 50 by 23, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3894828.5652
If we subtract 46 from 50, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
23 goes into 40 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 3894828.56521
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 14:
170 divided by 23 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 3894828.565217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 15:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3894828.5652173
Subtract 69 from 90 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.

Moving on to step 16:
If we divide 210 by 23, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 3894828.56521739
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.

The final result is 3894828.56521739 with a remainder of 3e-09.
