283574 divided by 23 
The aim is to understand the frequency of 23 in 283574.

Going ahead to step 1:
2 divided by 23 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 23

Advancing to step 2:
28 divided by 23 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 23 from 28 leaves us with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 23

Moving on to step 3:
If we divide 53 by 23, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 46 from 53 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 23

Going ahead to step 4:
When dividing 75 by 23, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 69 from 75 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 23

Moving on to step 5:
When dividing 67 by 23, we get 2 with a remainder of 21.
The next digit of our result is 2. 
Result so far: 1232.0
Subtract 46 from 67 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 23

Moving on to step 6:
If we divide 214 by 23, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 12329.0
Deduct 207 from 214 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.

Let's proceed to step 7:
70 divided by 23 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 12329.3
Deduct 69 from 70 and we're left 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.

On to step 8:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 12329.3
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 9:
The number 23 fits into 100 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 12329.304
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.

Step 10:
When dividing 80 by 23, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 12329.3043
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 11:
When dividing 110 by 23, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 12329.30434
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.

Going ahead to step 12:
23 can be fit into 180 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 12329.304347
Subtracting 161 from 180 leaves us 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.

Going ahead to step 13:
When dividing 190 by 23, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 12329.3043478
If we take 184 away from 190, we end up 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.

Moving on to step 14:
If we divide 60 by 23, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 12329.30434782
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 12329.30434782, with a leftover of 1.4e-08.
