490338 ÷ 23 
Our goal is to divide 490338 by 23.

Step 1:
23 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 23

Let's proceed to step 2:
If we divide 49 by 23, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 46 from 49 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 23

On to step 3:
23 goes into 30 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 23 away from 30, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 23

On to step 4:
If we divide 73 by 23, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 213.0
Deduct 69 from 73 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 23

Let's proceed to step 5:
The number 23 fits into 43 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 2131.0
Subtract 23 from 43 to get 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 23

Let's proceed to step 6:
23 goes into 208 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 21319.0
If we subtract 207 from 208, 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 7:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 21319.0
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.

Step 8:
23 goes into 100 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 21319.04
The remainder is 8 after subtracting 92 from 100.
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 9:
80 divided by 23 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 21319.043
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 10:
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: 21319.0434
If we take 92 away from 110, we end up 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.

Let's proceed to step 11:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 21319.04347
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
When dividing 190 by 23, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 21319.043478
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
23 goes into 60 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 21319.0434782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
23 goes into 140 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 21319.04347826
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.

The final result is 21319.04347826 with a remainder of 2e-09.
