We divide 8642886 by 878
We want to figure out the number of times 8642886 can be divided by 878.

Advancing to step 1:
The number 878 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 878

Going ahead to step 2:
86 divided by 878 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 878

On to step 3:
If we divide 864 by 878, we get 0 and a remainder of 864.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 864 leaves us with 864.
Include the next digit (2) from the dividend after 864, then repeat: 8642 / 878

Let's proceed to step 4:
If we divide 8642 by 878, we get 9 and a remainder of 740.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7902 from 8642 leaves us with 740.
Append the next digit (8) from the dividend to 740 and continue with: 7408 / 878

Going ahead to step 5:
878 can be fit into 7408 8 times, resulting in a remainder of 384.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
The remainder is 384 after subtracting 7024 from 7408.
Bring next digit (8) of the dividend behind the 384 and repeat the process: 3848 / 878

On to step 6:
878 can be fit into 3848 4 times, resulting in a remainder of 336.
Use 4 as the next digit of our solution. 
Result so far: 984.0
If we take 3512 away from 3848, we end up with 336.
Fetch the next digit (6) from the dividend, attach it to 336 and continue: 3366 / 878

On to step 7:
The number 878 fits into 3366 3 times, leaving a remainder of 732.
The number 3 becomes the next digit in our result. 
Result so far: 9843.0
If we subtract 2634 from 3366, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Going ahead to step 8:
When dividing 7320 by 878, we get 8 with a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 9843.8
Subtracting 7024 from 7320 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 9:
2960 divided by 878 is 3 with a remainder of 326.
Record the quotient 3 as the next digit in the result. 
Result so far: 9843.83
If we take 2634 away from 2960, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 10:
3260 divided by 878 is 3 with a remainder of 626.
Put 3 as the next digit of the answer. 
Result so far: 9843.833
If we subtract 2634 from 3260, we get 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

The final result is 9843.833 with a remainder of 0.0626.
