We're dividing 77277485 by 817 
Our goal is to divide 77277485 by 817.

Advancing to step 1:
When dividing 7 by 817, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 817

Going ahead to step 2:
817 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 817

Advancing to step 3:
817 can be fit into 772 0 times, resulting in a remainder of 772.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 772, we get 772.
Grab the next digit (7) from the dividend, add it to 772, then carry on: 7727 / 817

Going ahead to step 4:
The number 817 fits into 7727 9 times, leaving a remainder of 374.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7353 from 7727, we get 374.
Bring next digit (7) of the dividend behind the 374 and repeat the process: 3747 / 817

Moving on to step 5:
If we divide 3747 by 817, we get 4 and a remainder of 479.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 3268 from 3747, we get 479.
Take the next digit (4) from the dividend and append it to 479, then repeat: 4794 / 817

Moving on to step 6:
When dividing 4794 by 817, we get 5 with a remainder of 709.
The number 5 becomes the next digit in our result. 
Result so far: 945.0
Subtract 4085 from 4794 to get 709.
Bring next digit (8) of the dividend behind the 709 and repeat the process: 7098 / 817

On to step 7:
7098 divided by 817 is 8 with a remainder of 562.
Record the quotient 8 as the next digit in the result. 
Result so far: 9458.0
Deduct 6536 from 7098 and we're left with 562.
Bring next digit (5) of the dividend behind the 562 and repeat the process: 5625 / 817

Moving on to step 8:
817 can be fit into 5625 6 times, resulting in a remainder of 723.
Record the quotient 6 as the next digit in the result. 
Result so far: 94586.0
Subtract 4902 from 5625 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

On to step 9:
The number 817 fits into 7230 8 times, leaving a remainder of 694.
The number 8 becomes the next digit in our result. 
Result so far: 94586.8
Subtracting 6536 from 7230 leaves us with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

On to step 10:
817 goes into 6940 8 times with a remainder of 404.
The next digit of our result is 8. 
Result so far: 94586.88
The remainder is 404 after subtracting 6536 from 6940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final result is 94586.88 with a remainder of 0.404.
