We're dividing 519781 by 80 
We're looking to find how many times 80 goes into 519781.

Moving on to step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 80

Let's proceed to step 2:
When dividing 51 by 80, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 80

Going ahead to step 3:
If we divide 519 by 80, we get 6 and a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 480 from 519 leaves us with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 80

Advancing to step 4:
If we divide 397 by 80, we get 4 and a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 64.0
Deduct 320 from 397 and we're left with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 80

Going ahead to step 5:
80 can be fit into 778 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 649.0
Subtract 720 from 778 to get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 80

Step 6:
If we divide 581 by 80, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 6497.0
If we take 560 away from 581, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
80 goes into 210 2 times with a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 6497.2
Subtracting 160 from 210 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
If we divide 500 by 80, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6497.26
The remainder is 20 after subtracting 480 from 500.
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 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 6497.262
If we take 160 away from 200, 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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6497.2625
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.

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: 6497.2625
If we subtract 0 from 0, 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.

Going ahead to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6497.2625
If we subtract 0 from 0, 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.

After the division, we end up with 6497.2625 and a remainder of 0.0.
