450128 divided by 23 
The aim is to understand the frequency of 23 in 450128.

Step 1:
4 divided by 23 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 23

Step 2:
When dividing 45 by 23, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 22 after subtracting 23 from 45.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 23

Let's proceed to step 3:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 207 from 220 and we're left with 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 23

On to step 4:
23 goes into 131 5 times with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Deduct 115 from 131 and we're left with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 23

Advancing to step 5:
23 can be fit into 162 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 1957.0
Subtract 161 from 162 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Going ahead to step 6:
The number 23 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 19570.0
Deduct 0 from 18 and we're left 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.

Advancing to step 7:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 19570.7
Deduct 161 from 180 and we're left 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 8:
190 divided by 23 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 19570.78
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 19570.782
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
If we divide 140 by 23, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 19570.7826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 19570.7826
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
If we divide 200 by 23, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 19570.782608
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
When dividing 160 by 23, we get 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 19570.7826086
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
When dividing 220 by 23, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 19570.78260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 19570.78260869, and the remainder is 1.3e-08.
