820830 ÷ 77 
We want to divide 820830 by 77.

Advancing to step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 77

Let's proceed to step 2:
77 goes into 82 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 77 from 82 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 77

Going ahead to step 3:
77 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 50, we end up with 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 77

Moving on to step 4:
If we divide 508 by 77, we get 6 and a remainder of 46.
The next digit of our result is 6. 
Result so far: 106.0
Deduct 462 from 508 and we're left with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 77

Moving on to step 5:
If we divide 463 by 77, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 1066.0
The remainder is 1 after subtracting 462 from 463.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 77

Advancing to step 6:
10 divided by 77 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10660.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
The number 77 fits into 100 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 10660.1
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
If we divide 230 by 77, we get 2 and a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 10660.12
Deduct 154 from 230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
77 goes into 760 9 times with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 10660.129
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
670 divided by 77 is 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 10660.1298
If we subtract 616 from 670, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
77 goes into 540 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 10660.12987
The remainder is 1 after subtracting 539 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
77 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10660.12987
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
100 divided by 77 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 10660.1298701
The remainder is 23 after subtracting 77 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
77 can be fit into 230 2 times, resulting in a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 10660.12987012
If we take 154 away from 230, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

In conclusion, the division gives 10660.12987012 with a balance of 7.6e-08.
