We're dividing 510793 by 80 
We want to divide 510793 by 80.

Going ahead to step 1:
5 divided by 80 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 80

Going ahead to step 2:
51 divided by 80 is 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 80

On to step 3:
The number 80 fits into 510 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 480 from 510, we get 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 80

On to step 4:
80 goes into 307 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Deduct 240 from 307 and we're left with 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 80

Moving on to step 5:
80 goes into 679 8 times with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
If we subtract 640 from 679, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 80

Moving on to step 6:
The number 80 fits into 393 4 times, leaving a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 6384.0
Subtract 320 from 393 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 7:
The number 80 fits into 730 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 6384.9
If we subtract 720 from 730, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 6384.91
If we take 80 away from 100, 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.

Step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 6384.912
Subtract 160 from 200 to get 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 10:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6384.9125
Subtract 400 from 400 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.

On to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6384.9125
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.

Moving on to step 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6384.9125
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.

The final outcome is 6384.9125, with a leftover of 0.0.
