Let's divide 505780 by 77
We want to divide 505780 by 77.

On to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 77

On to step 2:
50 divided by 77 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Bring next digit (5) of the dividend behind the 50 and repeat the process: 505 / 77

On to step 3:
When dividing 505 by 77, we get 6 with a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 462 away from 505, we end up with 43.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 77

Step 4:
The number 77 fits into 437 5 times, leaving a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 65.0
The remainder is 52 after subtracting 385 from 437.
Grab the next digit (8) from the dividend, add it to 52, then carry on: 528 / 77

Going ahead to step 5:
77 goes into 528 6 times with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 656.0
Subtracting 462 from 528 leaves us with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 77

On to step 6:
77 can be fit into 660 8 times, resulting in a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 6568.0
The remainder is 44 after subtracting 616 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
When dividing 440 by 77, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 6568.5
Subtract 385 from 440 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 8:
The number 77 fits into 550 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 6568.57
Subtract 539 from 550 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
If we divide 110 by 77, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 6568.571
If we subtract 77 from 110, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
77 goes into 330 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 6568.5714
Subtracting 308 from 330 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 11:
77 can be fit into 220 2 times, resulting in a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 6568.57142
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
The number 77 fits into 660 8 times, leaving a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 6568.571428
The remainder is 44 after subtracting 616 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
If we divide 440 by 77, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 6568.5714285
The remainder is 55 after subtracting 385 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
If we divide 550 by 77, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 6568.57142857
Deduct 539 from 550 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 6568.57142857 with a remainder of 1.1e-08.
