493665 ÷ 23 
The aim is to understand the frequency of 23 in 493665.

Step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 23

Let's proceed to step 2:
The number 23 fits into 49 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 3 after subtracting 46 from 49.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 23

On to step 3:
23 goes into 33 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtract 23 from 33 to get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 23

Step 4:
When dividing 106 by 23, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Subtract 92 from 106 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 23

Step 5:
When dividing 146 by 23, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 2146.0
Deduct 138 from 146 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 23

On to step 6:
85 divided by 23 is 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 21463.0
If we subtract 69 from 85, 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.

Going ahead to step 7:
23 goes into 160 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 21463.6
Subtracting 138 from 160 leaves us 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.

On to step 8:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 21463.69
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.

Step 9:
23 goes into 130 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 21463.695
If we take 115 away from 130, we end up 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.

Advancing to step 10:
When dividing 150 by 23, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 21463.6956
Deduct 138 from 150 and we're left 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.

Moving on to step 11:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 21463.69565
Deduct 115 from 120 and we're left with 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 12:
50 divided by 23 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 21463.695652
If we take 46 away from 50, we end up 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.

On to step 13:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 21463.6956521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
170 divided by 23 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 21463.69565217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 21463.69565217 with a remainder of 9e-09.
