820512 ÷ 77 
Let's see how many times 77 fits into 820512.

Going ahead to step 1:
8 divided by 77 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 77

On to step 2:
If we divide 82 by 77, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 77 from 82 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 77

On to step 3:
The number 77 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 50 leaves us with 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 77

On to step 4:
505 divided by 77 is 6 with a remainder of 43.
The next digit of our result is 6. 
Result so far: 106.0
The remainder is 43 after subtracting 462 from 505.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 77

Advancing to step 5:
431 divided by 77 is 5 with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 1065.0
Subtracting 385 from 431 leaves us with 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 77

Going ahead to step 6:
462 divided by 77 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 10656.0
If we take 462 away from 462, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
If we divide 0 by 77, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10656.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 77 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10656.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10656.0 with a remainder of 0.0.
