We're dividing 580400 by 23 
Let's see how many times 23 fits into 580400.

Let's proceed to step 1:
5 divided by 23 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 23

Moving on to step 2:
23 goes into 58 2 times with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 46 from 58 to get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 23

Step 3:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 115 from 120 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 23

Moving on to step 4:
23 can be fit into 54 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 252.0
If we take 46 away from 54, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 23

Let's proceed to step 5:
When dividing 80 by 23, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 2523.0
The remainder is 11 after subtracting 69 from 80.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 23

Going ahead to step 6:
23 goes into 110 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 25234.0
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.

Step 7:
23 goes into 180 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 25234.7
Subtracting 161 from 180 leaves us with 19.
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 8:
190 divided by 23 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 25234.78
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.

Step 9:
60 divided by 23 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 25234.782
If we subtract 46 from 60, we get 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 10:
140 divided by 23 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 25234.7826
Subtracting 138 from 140 leaves us 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.

Let's proceed to step 11:
When dividing 20 by 23, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25234.7826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
When dividing 200 by 23, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25234.782608
If we subtract 184 from 200, 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 13:
If we divide 160 by 23, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 25234.7826086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
23 goes into 220 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 25234.78260869
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.

After the division, we end up with 25234.78260869 and a remainder of 1.3e-08.
