877286 ÷ 80 
Let's see how many times 80 fits into 877286.

Going ahead to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 80

Advancing to step 2:
80 goes into 87 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 80 from 87 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 80

Step 3:
The number 80 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 80

On to step 4:
80 can be fit into 772 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Subtract 720 from 772 to get 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 80

Going ahead to step 5:
If we divide 528 by 80, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1096.0
If we subtract 480 from 528, we get 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 80

On to step 6:
486 divided by 80 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 10966.0
If we take 480 away from 486, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 80, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10966.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 10966.07
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10966.075
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10966.075
If we subtract 0 from 0, we get 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 11:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10966.075
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.

The final outcome is 10966.075, with a leftover of 0.0.
