18313050 ÷ 580 
We want to figure out the number of times 18313050 can be divided by 580.

Advancing to step 1:
580 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 580

Advancing to step 2:
The number 580 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 580

Going ahead to step 3:
If we divide 183 by 580, we get 0 and a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 183, we get 183.
Append the next digit (1) from the dividend to 183 and continue with: 1831 / 580

Going ahead to step 4:
The number 580 fits into 1831 3 times, leaving a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1740 from 1831 to get 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 580

Moving on to step 5:
If we divide 913 by 580, we get 1 and a remainder of 333.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 580 from 913 to get 333.
Include the next digit (0) from the dividend after 333, then repeat: 3330 / 580

Moving on to step 6:
When dividing 3330 by 580, we get 5 with a remainder of 430.
Put 5 as the next digit of the answer. 
Result so far: 315.0
If we subtract 2900 from 3330, we get 430.
Include the next digit (5) from the dividend after 430, then repeat: 4305 / 580

Advancing to step 7:
The number 580 fits into 4305 7 times, leaving a remainder of 245.
The number 7 becomes the next digit in our result. 
Result so far: 3157.0
Deduct 4060 from 4305 and we're left with 245.
Bring next digit (0) of the dividend behind the 245 and repeat the process: 2450 / 580

Step 8:
If we divide 2450 by 580, we get 4 and a remainder of 130.
Record the quotient 4 as the next digit in the result. 
Result so far: 31574.0
Deduct 2320 from 2450 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 9:
580 can be fit into 1300 2 times, resulting in a remainder of 140.
Use 2 as the next digit of our solution. 
Result so far: 31574.2
Subtracting 1160 from 1300 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 10:
If we divide 1400 by 580, we get 2 and a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 31574.22
Subtract 1160 from 1400 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 31574.22 with a remainder of 0.24.
