31580 ÷ 25 
We want to divide 31580 by 25.

On to step 1:
When dividing 3 by 25, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 25

Going ahead to step 2:
If we divide 31 by 25, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 25 from 31 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 25

Step 3:
25 can be fit into 65 2 times, resulting in a remainder of 15.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 15 after subtracting 50 from 65.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 25

Advancing to step 4:
158 divided by 25 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 126.0
Subtract 150 from 158 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 25

On to step 5:
25 can be fit into 80 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 1263.0
Subtracting 75 from 80 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
If we divide 50 by 25, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1263.2
Subtracting 50 from 50 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1263.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1263.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1263.2 and a remainder of 0.0.
