591405 divided by 23 
Our goal is to divide 591405 by 23.

Going ahead to step 1:
If we divide 5 by 23, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 23

On to step 2:
23 goes into 59 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 13 after subtracting 46 from 59.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 23

On to step 3:
If we divide 131 by 23, we get 5 and a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 16 after subtracting 115 from 131.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 23

On to step 4:
The number 23 fits into 164 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 257.0
The remainder is 3 after subtracting 161 from 164.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 23

Let's proceed to step 5:
If we divide 30 by 23, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 2571.0
Subtract 23 from 30 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 23

On to step 6:
23 can be fit into 75 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 25713.0
Subtracting 69 from 75 leaves us 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.

Step 7:
60 divided by 23 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 25713.2
Subtract 46 from 60 to 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.

Let's proceed to step 8:
When dividing 140 by 23, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 25713.26
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 25713.26
If we subtract 0 from 20, we 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.

Step 10:
If we divide 200 by 23, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 25713.2608
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.

Moving on to step 11:
23 goes into 160 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 25713.26086
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
23 goes into 220 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 25713.260869
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
130 divided by 23 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 25713.2608695
If we take 115 away from 130, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 25713.26086956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 25713.26086956, with a leftover of 1.2e-08.
