We're dividing 487580 by 23 
We want to figure out the number of times 487580 can be divided by 23.

Moving on to step 1:
4 divided by 23 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 23

Advancing to step 2:
If we divide 48 by 23, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 46 from 48, we get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 23

Let's proceed to step 3:
When dividing 27 by 23, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 23 from 27 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 23

Step 4:
23 can be fit into 45 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 211.0
The remainder is 22 after subtracting 23 from 45.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 23

On to step 5:
When dividing 228 by 23, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 2119.0
The remainder is 21 after subtracting 207 from 228.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 23

Let's proceed to step 6:
210 divided by 23 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 21199.0
Subtracting 207 from 210 leaves us 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.

Going ahead to step 7:
23 goes into 30 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 21199.1
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 8:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 21199.13
Subtracting 69 from 70 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 21199.13
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 10:
100 divided by 23 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 21199.1304
If we subtract 92 from 100, we 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 11:
23 goes into 80 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 21199.13043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
If we divide 110 by 23, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 21199.130434
Subtracting 92 from 110 leaves us 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.

Moving on to step 13:
The number 23 fits into 180 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 21199.1304347
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.

On to step 14:
190 divided by 23 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 21199.13043478
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 21199.13043478 with a remaining 6e-09.
