We're dividing 505055 by 77 
Let's see how many times 77 fits into 505055.

Step 1:
77 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 77

Moving on to step 2:
77 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 77

Moving on to step 3:
The number 77 fits into 505 6 times, leaving a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 462 from 505, we get 43.
Include the next digit (0) from the dividend after 43, then repeat: 430 / 77

Let's proceed to step 4:
77 goes into 430 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we subtract 385 from 430, we get 45.
Bring next digit (5) of the dividend behind the 45 and repeat the process: 455 / 77

Advancing to step 5:
If we divide 455 by 77, we get 5 and a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 655.0
If we take 385 away from 455, we end up with 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 77

Let's proceed to step 6:
77 can be fit into 705 9 times, resulting in a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 6559.0
If we take 693 away from 705, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
When dividing 120 by 77, we get 1 with a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 6559.1
Subtracting 77 from 120 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
The number 77 fits into 430 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 6559.15
Subtract 385 from 430 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
If we divide 450 by 77, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 6559.155
Deduct 385 from 450 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 6559.155 with a remainder of 0.0065.
