489397 divided by 23 
We want to figure out the number of times 489397 can be divided by 23.

Advancing to step 1:
4 divided by 23 is 0 with 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.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 23

Step 2:
48 divided by 23 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 46 away from 48, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 23

Moving on to step 3:
29 divided by 23 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 23 from 29 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 23

Going ahead to step 4:
If we divide 63 by 23, we get 2 and a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 212.0
If we take 46 away from 63, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 23

Let's proceed to step 5:
When dividing 179 by 23, we get 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 2127.0
Subtract 161 from 179 to get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 23

Let's proceed to step 6:
When dividing 187 by 23, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 21278.0
Deduct 184 from 187 and we're left with 3.
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 7:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 21278.1
Subtracting 23 from 30 leaves us 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.

Advancing to step 8:
When dividing 70 by 23, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 21278.13
Subtract 69 from 70 to 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 9:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 21278.13
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
23 goes into 100 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 21278.1304
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
23 goes into 80 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 21278.13043
Subtract 69 from 80 to 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 12:
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: 21278.130434
Subtract 92 from 110 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
23 goes into 180 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 21278.1304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 14:
190 divided by 23 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 21278.13043478
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 21278.13043478 with a remaining 6e-09.
