454570 ÷ 23 
The aim is to understand the frequency of 23 in 454570.

Advancing to step 1:
23 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 23

Step 2:
23 goes into 45 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 22 after subtracting 23 from 45.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 23

Moving on to step 3:
23 can be fit into 224 9 times, resulting in a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 207 from 224 to get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 23

Going ahead to step 4:
If we divide 175 by 23, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
Subtracting 161 from 175 leaves us with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 23

Let's proceed to step 5:
The number 23 fits into 147 6 times, leaving a remainder of 9.
The next digit of our result is 6. 
Result so far: 1976.0
The remainder is 9 after subtracting 138 from 147.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 23

Step 6:
If we divide 90 by 23, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 19763.0
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 23, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 19763.9
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 19763.91
Subtract 23 from 30 to get 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 9:
70 divided by 23 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 19763.913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
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: 19763.913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
23 goes into 100 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 19763.91304
If we subtract 92 from 100, we 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.

On to step 12:
80 divided by 23 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 19763.913043
Subtracting 69 from 80 leaves us 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 13:
110 divided by 23 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 19763.9130434
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 14:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 19763.91304347
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.

Our division results in 19763.91304347 with a remaining 1.9e-08.
