We look at the division of 249484 by 80 
We want to divide 249484 by 80.

Let's proceed to step 1:
When dividing 2 by 80, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 80

Advancing to step 2:
If we divide 24 by 80, we get 0 and a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 80

Moving on to step 3:
80 goes into 249 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 9 after subtracting 240 from 249.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 80

Step 4:
When dividing 94 by 80, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 80 from 94 leaves us with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 80

Let's proceed to step 5:
80 goes into 148 1 times with a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 311.0
If we take 80 away from 148, we end up with 68.
Grab the next digit (4) from the dividend, add it to 68, then carry on: 684 / 80

On to step 6:
If we divide 684 by 80, we get 8 and a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 3118.0
Subtracting 640 from 684 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
When dividing 440 by 80, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 3118.5
The remainder is 40 after subtracting 400 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 3118.55
If we subtract 400 from 400, we 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.

The quotient of the division is 3118.55, and the remainder is 0.0.
