Let's divide 27978 by 80
We want to figure out the number of times 27978 can be divided by 80.

Going ahead to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 80

Going ahead to step 2:
The number 80 fits into 27 0 times, leaving a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 80

Advancing to step 3:
279 divided by 80 is 3 with a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 240 away from 279, we end up with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 80

Going ahead to step 4:
When dividing 397 by 80, we get 4 with a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtracting 320 from 397 leaves us with 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 80

Let's proceed to step 5:
The number 80 fits into 778 9 times, leaving a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 349.0
Subtract 720 from 778 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 6:
The number 80 fits into 580 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 349.7
If we take 560 away from 580, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 349.72
Deduct 160 from 200 and we're left 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.

On to step 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 349.725
Deduct 400 from 400 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.

Step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 349.725
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 349.725
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.

Our division results in 349.725 with a remaining 0.0.
