663145 divided by 23 
We want to divide 663145 by 23.

Step 1:
23 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 23

Let's proceed to step 2:
23 can be fit into 66 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 46 from 66 and we're left with 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 23

Moving on to step 3:
The number 23 fits into 203 8 times, leaving a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 184 away from 203, we end up with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 23

Going ahead to step 4:
191 divided by 23 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 288.0
Subtracting 184 from 191 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 23

Moving on to step 5:
23 goes into 74 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 2883.0
Subtract 69 from 74 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 23

Let's proceed to step 6:
23 goes into 55 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 28832.0
The remainder is 9 after subtracting 46 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 23, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 28832.3
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
210 divided by 23 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 28832.39
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 23 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 28832.391
Deduct 23 from 30 and we're left with 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 10:
23 goes into 70 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 28832.3913
If we subtract 69 from 70, we 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 11:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 28832.3913
If we subtract 0 from 10, we 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.

Moving on to step 12:
When dividing 100 by 23, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 28832.391304
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.

Going ahead to step 13:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 28832.3913043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
When dividing 110 by 23, we get 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 28832.39130434
Deduct 92 from 110 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.

Our division results in 28832.39130434 with a remaining 1.8e-08.
