780800 ÷ 25 
Our goal is to divide 780800 by 25.

On to step 1:
25 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 25

On to step 2:
78 divided by 25 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 75 from 78, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 25

Advancing to step 3:
The number 25 fits into 30 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 25 from 30 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 25

Advancing to step 4:
58 divided by 25 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 312.0
Subtracting 50 from 58 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 25

Advancing to step 5:
25 can be fit into 80 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3123.0
Subtracting 75 from 80 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 25

Step 6:
50 divided by 25 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 31232.0
Subtract 50 from 50 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 31232.0
Deduct 0 from 0 and we're left 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.

Moving on to step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31232.0
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.

The final result is 31232.0 with a remainder of 0.0.
