513779 ÷ 80 
Let's see how many times 80 fits into 513779.

Going ahead to step 1:
80 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 80

Going ahead to step 2:
When dividing 51 by 80, we get 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 80

Step 3:
If we divide 513 by 80, we get 6 and a remainder of 33.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 33 after subtracting 480 from 513.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 80

Advancing to step 4:
When dividing 337 by 80, we get 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Deduct 320 from 337 and we're left with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 80

Moving on to step 5:
177 divided by 80 is 2 with a remainder of 17.
The next digit of our result is 2. 
Result so far: 642.0
Subtract 160 from 177 to get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 80

On to step 6:
If we divide 179 by 80, we get 2 and a remainder of 19.
The next digit of our result is 2. 
Result so far: 6422.0
Subtract 160 from 179 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 80, we get 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 6422.2
Deduct 160 from 190 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
80 goes into 300 3 times with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 6422.23
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 6422.237
Subtracting 560 from 600 leaves us 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 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6422.2375
Subtracting 400 from 400 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.

Going ahead to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6422.2375
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.

Moving on to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6422.2375
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.

The final outcome is 6422.2375, with a leftover of 0.0.
