518475 divided by 80 
Our goal is to divide 518475 by 80.

On to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 80

Step 2:
80 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (8) of the dividend behind the 51 and repeat the process: 518 / 80

Advancing to step 3:
The number 80 fits into 518 6 times, leaving a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 480 away from 518, we end up with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 80

Let's proceed to step 4:
The number 80 fits into 384 4 times, leaving a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 64 after subtracting 320 from 384.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 80

Advancing to step 5:
If we divide 647 by 80, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 648.0
The remainder is 7 after subtracting 640 from 647.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 80

Advancing to step 6:
75 divided by 80 is 0 with a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 6480.0
Subtracting 0 from 75 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
80 goes into 750 9 times with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 6480.9
Deduct 720 from 750 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.

Moving on to step 8:
80 goes into 300 3 times with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 6480.93
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.

On to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 6480.937
Subtract 560 from 600 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.

Let's proceed to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6480.9375
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.

Advancing to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6480.9375
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.

Advancing to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 6480.9375
If we take 0 away from 0, we end up 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 quotient of the division is 6480.9375, and the remainder is 0.0.
