We're dividing 550071 by 77 
Let's see how many times 77 fits into 550071.

Going ahead to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 77

Going ahead to step 2:
77 goes into 55 0 times with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 77

Going ahead to step 3:
550 divided by 77 is 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 539 from 550 and we're left with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 77

On to step 4:
77 can be fit into 110 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 77 from 110, we get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 77

Advancing to step 5:
77 goes into 337 4 times with a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 714.0
The remainder is 29 after subtracting 308 from 337.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 77

Going ahead to step 6:
77 can be fit into 291 3 times, resulting in a remainder of 60.
The next digit of our result is 3. 
Result so far: 7143.0
Deduct 231 from 291 and we're left 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 7:
If we divide 600 by 77, we get 7 and a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 7143.7
Subtract 539 from 600 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
If we divide 610 by 77, we get 7 and a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 7143.77
Deduct 539 from 610 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 7143.77, and the remainder is 0.071.
