We look at the division of 519420 by 77 
We want to divide 519420 by 77.

Step 1:
When dividing 5 by 77, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 77

On to step 2:
77 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 77

Let's proceed to step 3:
When dividing 519 by 77, we get 6 with a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 57 after subtracting 462 from 519.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 77

On to step 4:
77 can be fit into 574 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 67.0
The remainder is 35 after subtracting 539 from 574.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 77

Advancing to step 5:
77 can be fit into 352 4 times, resulting in a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 674.0
If we subtract 308 from 352, we get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 77

Going ahead to step 6:
77 can be fit into 440 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 6745.0
Subtracting 385 from 440 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
77 can be fit into 550 7 times, resulting in a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 6745.7
If we take 539 away from 550, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
77 goes into 110 1 times with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 6745.71
If we subtract 77 from 110, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
330 divided by 77 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 6745.714
Subtracting 308 from 330 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
When dividing 220 by 77, we get 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 6745.7142
Subtracting 154 from 220 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
The number 77 fits into 660 8 times, leaving a remainder of 44.
The next digit of our result is 8. 
Result so far: 6745.71428
If we subtract 616 from 660, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
440 divided by 77 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 6745.714285
If we subtract 385 from 440, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 13:
When dividing 550 by 77, we get 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 6745.7142857
Subtracting 539 from 550 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 14:
110 divided by 77 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 6745.71428571
If we take 77 away from 110, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

In conclusion, the division gives 6745.71428571 with a balance of 3.3e-08.
