8784279 ÷ 878 
We want to divide 8784279 by 878.

Let's proceed to step 1:
878 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 878

Advancing to step 2:
878 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 878

On to step 3:
878 can be fit into 878 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 878 from 878 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 878

Moving on to step 4:
When dividing 4 by 878, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 878

Advancing to step 5:
The number 878 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 878

Let's proceed to step 6:
427 divided by 878 is 0 with a remainder of 427.
Put 0 as the next digit of the answer. 
Result so far: 1000.0
Subtract 0 from 427 to get 427.
Fetch the next digit (9) from the dividend, attach it to 427 and continue: 4279 / 878

On to step 7:
When dividing 4279 by 878, we get 4 with a remainder of 767.
Put 4 as the next digit of the answer. 
Result so far: 10004.0
Subtracting 3512 from 4279 leaves us with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Step 8:
878 goes into 7670 8 times with a remainder of 646.
Put 8 as the next digit of the answer. 
Result so far: 10004.8
If we subtract 7024 from 7670, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 9:
If we divide 6460 by 878, we get 7 and a remainder of 314.
Record the quotient 7 as the next digit in the result. 
Result so far: 10004.87
The remainder is 314 after subtracting 6146 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 10:
3140 divided by 878 is 3 with a remainder of 506.
Write down 3 as next digit of the result. 
Result so far: 10004.873
Deduct 2634 from 3140 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Going ahead to step 11:
878 can be fit into 5060 5 times, resulting in a remainder of 670.
Use 5 as the next digit of our solution. 
Result so far: 10004.8735
If we subtract 4390 from 5060, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 12:
6700 divided by 878 is 7 with a remainder of 554.
The next digit of our result is 7. 
Result so far: 10004.87357
Subtract 6146 from 6700 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 13:
5540 divided by 878 is 6 with a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 10004.873576
If we take 5268 away from 5540, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 14:
878 goes into 2720 3 times with a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 10004.8735763
If we subtract 2634 from 2720, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 15:
When dividing 860 by 878, we get 0 with a remainder of 860.
Use 0 as the next digit of our solution. 
Result so far: 10004.8735763
If we take 0 away from 860, we end up with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

The final outcome is 10004.8735763, with a leftover of 8.6e-07.
