878735 divided by 80 
We're looking to find how many times 80 goes into 878735.

On to step 1:
8 divided by 80 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 80

Step 2:
When dividing 87 by 80, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 80 from 87 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 80

Let's proceed to step 3:
80 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 80

On to step 4:
80 goes into 787 9 times with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtracting 720 from 787 leaves us with 67.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 80

Moving on to step 5:
673 divided by 80 is 8 with a remainder of 33.
The next digit of our result is 8. 
Result so far: 1098.0
Subtracting 640 from 673 leaves us with 33.
Fetch the next digit (5) from the dividend, attach it to 33 and continue: 335 / 80

Moving on to step 6:
When dividing 335 by 80, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 10984.0
The remainder is 15 after subtracting 320 from 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 80, we get 1 with a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 10984.1
Subtracting 80 from 150 leaves us 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:
The number 80 fits into 700 8 times, leaving a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 10984.18
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.

Let's proceed to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 10984.187
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10984.1875
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.

Step 11:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10984.1875
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.

Advancing to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 10984.1875
Subtract 0 from 0 to 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.

Our division results in 10984.1875 with a remaining 0.0.
