We divide 503751 by 80
We want to divide 503751 by 80.

Step 1:
80 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 80

Moving on to step 2:
The number 80 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 80

Let's proceed to step 3:
If we divide 503 by 80, we get 6 and a remainder of 23.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 23 after subtracting 480 from 503.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 80

Step 4:
The number 80 fits into 237 2 times, leaving a remainder of 77.
Write down 2 as next digit of the result. 
Result so far: 62.0
The remainder is 77 after subtracting 160 from 237.
Bring next digit (5) of the dividend behind the 77 and repeat the process: 775 / 80

Step 5:
775 divided by 80 is 9 with a remainder of 55.
The next digit of our result is 9. 
Result so far: 629.0
If we take 720 away from 775, we end up with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 80

Let's proceed to step 6:
80 goes into 551 6 times with a remainder of 71.
The next digit of our result is 6. 
Result so far: 6296.0
Subtracting 480 from 551 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
When dividing 710 by 80, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 6296.8
If we take 640 away from 710, we end up 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 8:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 6296.88
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 6296.88 with a remainder of 0.06.
