78279 divided by 80 
We want to divide 78279 by 80.

Going ahead to step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 80

Going ahead to step 2:
80 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (2) from the dividend, add it to 78, then carry on: 782 / 80

Moving on to step 3:
80 goes into 782 9 times with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 720 from 782 to get 62.
Grab the next digit (7) from the dividend, add it to 62, then carry on: 627 / 80

On to step 4:
80 goes into 627 7 times with a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 560 from 627 leaves us with 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 80

Advancing to step 5:
The number 80 fits into 679 8 times, leaving a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 978.0
Subtract 640 from 679 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 6:
390 divided by 80 is 4 with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 978.4
Deduct 320 from 390 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
When dividing 700 by 80, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 978.48
Subtracting 640 from 700 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
The number 80 fits into 600 7 times, leaving a remainder of 40.
The next digit of our result is 7. 
Result so far: 978.487
If we take 560 away from 600, 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.

Let's proceed to step 9:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 978.4875
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.

Moving on to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 978.4875
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 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 978.4875
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 978.4875 with a remainder of 0.0.
