519390 divided by 80 
Let's see how many times 80 fits into 519390.

On to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 80

Going ahead to step 2:
The number 80 fits into 51 0 times, leaving a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 80

Let's proceed to step 3:
When dividing 519 by 80, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 480 from 519 to get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 80

Going ahead to step 4:
The number 80 fits into 393 4 times, leaving a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtract 320 from 393 to get 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 80

Advancing to step 5:
When dividing 739 by 80, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 649.0
Subtracting 720 from 739 leaves us with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 80

Advancing to step 6:
80 goes into 190 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 6492.0
If we subtract 160 from 190, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
The number 80 fits into 300 3 times, leaving a remainder of 60.
The next digit of our result is 3. 
Result so far: 6492.3
If we take 240 away from 300, we end up 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.

Going ahead to step 8:
80 goes into 600 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 6492.37
Deduct 560 from 600 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.

Going ahead to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6492.375
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6492.375
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.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6492.375
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 6492.375, with a leftover of 0.0.
