665579 ÷ 77 
Our goal is to divide 665579 by 77.

Moving on to step 1:
6 divided by 77 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 77

Moving on to step 2:
77 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 77

Moving on to step 3:
665 divided by 77 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 616 from 665 and we're left with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 77

Step 4:
77 can be fit into 495 6 times, resulting in a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 86.0
If we subtract 462 from 495, we get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 77

Going ahead to step 5:
77 goes into 337 4 times with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 864.0
If we subtract 308 from 337, we get 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 77

Going ahead to step 6:
77 goes into 299 3 times with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 8643.0
The remainder is 68 after subtracting 231 from 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 7:
77 can be fit into 680 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 8643.8
The remainder is 64 after subtracting 616 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
The number 77 fits into 640 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8643.88
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 8643.88 and a remainder of 0.024.
