We're dividing 877839 by 80 
Let's see how many times 80 fits into 877839.

Let's proceed to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 80

Step 2:
80 can be fit into 87 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 80 from 87 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 80

Advancing to step 3:
When dividing 77 by 80, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 77, we get 77.
Take the next digit (8) from the dividend and append it to 77, then repeat: 778 / 80

Moving on to step 4:
If we divide 778 by 80, we get 9 and a remainder of 58.
The next digit of our result is 9. 
Result so far: 109.0
If we take 720 away from 778, we end up with 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 80

Moving on to step 5:
If we divide 583 by 80, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 1097.0
Deduct 560 from 583 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 80

Step 6:
80 goes into 239 2 times with a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 10972.0
If we take 160 away from 239, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 7:
When dividing 790 by 80, we get 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 10972.9
If we take 720 away from 790, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
700 divided by 80 is 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 10972.98
Subtracting 640 from 700 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 10972.987
If we take 560 away from 600, we end up 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 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10972.9875
Deduct 400 from 400 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.

Moving on to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10972.9875
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.

Moving on to step 12:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10972.9875
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 10972.9875 with a balance of 0.0.
