180045 ÷ 23 
The aim is to understand the frequency of 23 in 180045.

On to step 1:
When dividing 1 by 23, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Let's proceed to step 2:
If we divide 18 by 23, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 23

Advancing to step 3:
If we divide 180 by 23, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 161 from 180 leaves us with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 23

Moving on to step 4:
If we divide 190 by 23, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 184 from 190 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 23

Going ahead to step 5:
When dividing 64 by 23, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 782.0
Subtracting 46 from 64 leaves us with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 23

On to step 6:
23 can be fit into 185 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 7828.0
Subtract 184 from 185 to 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.

Going ahead to step 7:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7828.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 7828.04
Subtract 92 from 100 to get 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 9:
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: 7828.043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 7828.0434
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
When dividing 180 by 23, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7828.04347
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 7828.043478
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.

On to step 13:
23 goes into 60 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 7828.0434782
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.

Step 14:
If we divide 140 by 23, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 7828.04347826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 7828.04347826 with a remainder of 2e-09.
