259924 ÷ 80 
Let's see how many times 80 fits into 259924.

On to step 1:
When dividing 2 by 80, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 80

Step 2:
If we divide 25 by 80, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 80

Step 3:
The number 80 fits into 259 3 times, leaving a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 19 after subtracting 240 from 259.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 80

On to step 4:
The number 80 fits into 199 2 times, leaving a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Deduct 160 from 199 and we're left with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 80

Advancing to step 5:
80 can be fit into 392 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 324.0
Subtract 320 from 392 to get 72.
Grab the next digit (4) from the dividend, add it to 72, then carry on: 724 / 80

On to step 6:
When dividing 724 by 80, we get 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 3249.0
Subtracting 720 from 724 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 80 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3249.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3249.05
If we take 400 away from 400, 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.

Let's proceed to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3249.05
Subtract 0 from 0 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.

Let's proceed to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3249.05
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.

The quotient of the division is 3249.05, and the remainder is 0.0.
