450728 ÷ 23 
The aim is to understand the frequency of 23 in 450728.

On 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
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 23

Advancing to step 2:
When dividing 45 by 23, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 23 away from 45, we end up with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 23

On to step 3:
When dividing 220 by 23, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 207 from 220 to get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 23

Moving on to step 4:
If we divide 137 by 23, we get 5 and a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Subtracting 115 from 137 leaves us with 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 23

On to step 5:
23 goes into 222 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 1959.0
Subtracting 207 from 222 leaves us with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 23

Let's proceed to step 6:
When dividing 158 by 23, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 19596.0
Subtracting 138 from 158 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.

Let's proceed to step 7:
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: 19596.8
If we subtract 184 from 200, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
23 goes into 160 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 19596.86
Deduct 138 from 160 and we're left with 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 9:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 19596.869
Deduct 207 from 220 and we're left 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.

Moving on to step 10:
If we divide 130 by 23, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 19596.8695
Subtracting 115 from 130 leaves us 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.

Going ahead to step 11:
If we divide 150 by 23, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 19596.86956
If we take 138 away from 150, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 19596.869565
Subtract 115 from 120 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
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: 19596.8695652
Subtracting 46 from 50 leaves us with 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 14:
40 divided by 23 is 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 19596.86956521
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.

The final result is 19596.86956521 with a remainder of 1.7e-08.
