Let's divide 557915 by 80
We want to divide 557915 by 80.

Advancing to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 80

Going ahead to step 2:
The number 80 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 80

On to step 3:
80 goes into 557 6 times with a remainder of 77.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 77 after subtracting 480 from 557.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 80

Let's proceed to step 4:
If we divide 779 by 80, we get 9 and a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 69.0
Subtracting 720 from 779 leaves us with 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 80

Step 5:
80 goes into 591 7 times with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 697.0
Subtract 560 from 591 to get 31.
Bring next digit (5) of the dividend behind the 31 and repeat the process: 315 / 80

Going ahead to step 6:
80 goes into 315 3 times with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 6973.0
Subtracting 240 from 315 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.

Going ahead to step 7:
80 goes into 750 9 times with a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 6973.9
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.

Advancing to step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
The next digit of our result is 3. 
Result so far: 6973.93
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 6973.937
If we subtract 560 from 600, we 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.

Advancing to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6973.9375
Deduct 400 from 400 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.

Going ahead to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6973.9375
If we subtract 0 from 0, we 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 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: 6973.9375
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.

The quotient of the division is 6973.9375, and the remainder is 0.0.
