23580039 ÷ 450 
Our goal is to divide 23580039 by 450.

Moving on to step 1:
If we divide 2 by 450, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 450

Step 2:
450 can be fit into 23 0 times, resulting in a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 450

Let's proceed to step 3:
When dividing 235 by 450, we get 0 with a remainder of 235.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 235, we end up with 235.
Fetch the next digit (8) from the dividend, attach it to 235 and continue: 2358 / 450

Step 4:
2358 divided by 450 is 5 with a remainder of 108.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 2250 away from 2358, we end up with 108.
Fetch the next digit (0) from the dividend, attach it to 108 and continue: 1080 / 450

Advancing to step 5:
450 goes into 1080 2 times with a remainder of 180.
The next digit of our result is 2. 
Result so far: 52.0
If we take 900 away from 1080, we end up with 180.
Include the next digit (0) from the dividend after 180, then repeat: 1800 / 450

Step 6:
The number 450 fits into 1800 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 524.0
If we take 1800 away from 1800, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 450

Advancing to step 7:
If we divide 3 by 450, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 5240.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 450

Let's proceed to step 8:
The number 450 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 52400.0
The remainder is 39 after subtracting 0 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
450 can be fit into 390 0 times, resulting in a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 52400.0
If we subtract 0 from 390, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 10:
If we divide 3900 by 450, we get 8 and a remainder of 300.
The next digit of our result is 8. 
Result so far: 52400.08
Deduct 3600 from 3900 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 11:
450 goes into 3000 6 times with a remainder of 300.
Record the quotient 6 as the next digit in the result. 
Result so far: 52400.086
Subtract 2700 from 3000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
When dividing 3000 by 450, we get 6 with a remainder of 300.
Record the quotient 6 as the next digit in the result. 
Result so far: 52400.0866
Subtract 2700 from 3000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 52400.0866, with a leftover of 0.003.
