556664 divided by 80 
Our goal is to divide 556664 by 80.

On to step 1:
5 divided by 80 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 80

Advancing to step 2:
If we divide 55 by 80, we get 0 and a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 80

Going ahead to step 3:
The number 80 fits into 556 6 times, leaving a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 480 from 556, we get 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 80

Advancing to step 4:
766 divided by 80 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 69.0
The remainder is 46 after subtracting 720 from 766.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 80

Moving on to step 5:
The number 80 fits into 466 5 times, leaving a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 695.0
If we subtract 400 from 466, we get 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 80

On to step 6:
664 divided by 80 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 6958.0
Subtracting 640 from 664 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
The number 80 fits into 240 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 6958.3
If we take 240 away from 240, 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.

Step 8:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6958.3
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.

Advancing to step 9:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6958.3
Deduct 0 from 0 and we're left 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 result is 6958.3 with a remainder of 0.0.
