We're dividing 550755 by 77 
We're looking to find how many times 77 goes into 550755.

Advancing to step 1:
5 divided by 77 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 77

Advancing to step 2:
55 divided by 77 is 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 77

Step 3:
If we divide 550 by 77, we get 7 and a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 539 from 550 to get 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 77

Let's proceed to step 4:
117 divided by 77 is 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtracting 77 from 117 leaves us with 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 77

On to step 5:
If we divide 405 by 77, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 715.0
Deduct 385 from 405 and we're left with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 77

Step 6:
If we divide 205 by 77, we get 2 and a remainder of 51.
Record the quotient 2 as the next digit in the result. 
Result so far: 7152.0
Subtracting 154 from 205 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
77 goes into 510 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 7152.6
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
The number 77 fits into 480 6 times, leaving a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 7152.66
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 7152.66 and a remainder of 0.018.
