We're dividing 830817 by 77 
Let's see how many times 77 fits into 830817.

On to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 77

Advancing to step 2:
When dividing 83 by 77, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 77 from 83 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 77

Advancing to step 3:
60 divided by 77 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 60 and we're left with 60.
Append the next digit (8) from the dividend to 60 and continue with: 608 / 77

Advancing to step 4:
When dividing 608 by 77, we get 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 539 away from 608, we end up with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 77

On to step 5:
77 can be fit into 691 8 times, resulting in a remainder of 75.
The next digit of our result is 8. 
Result so far: 1078.0
Subtract 616 from 691 to get 75.
Grab the next digit (7) from the dividend, add it to 75, then carry on: 757 / 77

Moving on to step 6:
757 divided by 77 is 9 with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 10789.0
Deduct 693 from 757 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.

Going ahead to step 7:
77 can be fit into 640 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 10789.8
Subtracting 616 from 640 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
240 divided by 77 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 10789.83
Subtracting 231 from 240 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 9:
If we divide 90 by 77, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 10789.831
Subtracting 77 from 90 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
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: 10789.8311
The remainder is 53 after subtracting 77 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

In conclusion, the division gives 10789.8311 with a balance of 0.00053.
