Let's divide 505390 by 77
Our goal is to divide 505390 by 77.

Going ahead to step 1:
When dividing 5 by 77, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 77

On to step 2:
50 divided by 77 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 77

On to step 3:
The number 77 fits into 505 6 times, leaving a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 462 from 505, we get 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 77

Let's proceed to step 4:
If we divide 433 by 77, we get 5 and a remainder of 48.
Use 5 as the next digit of our solution. 
Result so far: 65.0
The remainder is 48 after subtracting 385 from 433.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 77

Step 5:
The number 77 fits into 489 6 times, leaving a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 656.0
Subtracting 462 from 489 leaves us with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 77

Advancing to step 6:
The number 77 fits into 270 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 6563.0
Deduct 231 from 270 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
77 can be fit into 390 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 6563.5
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
If we divide 50 by 77, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6563.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
77 can be fit into 500 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 6563.506
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
380 divided by 77 is 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 6563.5064
Deduct 308 from 380 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
77 can be fit into 720 9 times, resulting in a remainder of 27.
The next digit of our result is 9. 
Result so far: 6563.50649
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
77 goes into 270 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 6563.506493
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
390 divided by 77 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6563.5064935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
When dividing 50 by 77, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6563.5064935
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 6563.5064935 and a remainder of 5e-08.
