Let's divide 520456 by 77
We're looking to find how many times 77 goes into 520456.

Moving on to step 1:
If we divide 5 by 77, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 77

Moving on to step 2:
52 divided by 77 is 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 77

On to step 3:
77 goes into 520 6 times with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 58 after subtracting 462 from 520.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 77

Advancing to step 4:
When dividing 584 by 77, we get 7 with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Deduct 539 from 584 and we're left with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 77

Step 5:
77 can be fit into 455 5 times, resulting in a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 675.0
The remainder is 70 after subtracting 385 from 455.
Bring next digit (6) of the dividend behind the 70 and repeat the process: 706 / 77

Advancing to step 6:
77 goes into 706 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 6759.0
If we subtract 693 from 706, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 77, we get 1 and a remainder of 53.
The next digit of our result is 1. 
Result so far: 6759.1
Deduct 77 from 130 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 8:
The number 77 fits into 530 6 times, leaving a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 6759.16
Deduct 462 from 530 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
The number 77 fits into 680 8 times, leaving a remainder of 64.
The next digit of our result is 8. 
Result so far: 6759.168
Deduct 616 from 680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
The number 77 fits into 640 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 6759.1688
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 6759.1688 and a remainder of 0.00024.
