Let's divide 829878 by 84
We want to divide 829878 by 84.

Advancing to step 1:
84 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 84

Advancing to step 2:
82 divided by 84 is 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Bring next digit (9) of the dividend behind the 82 and repeat the process: 829 / 84

Let's proceed to step 3:
829 divided by 84 is 9 with a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 756 away from 829, we end up with 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 84

Let's proceed to step 4:
When dividing 738 by 84, we get 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 672 from 738 and we're left with 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 84

Moving on to step 5:
The number 84 fits into 667 7 times, leaving a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 987.0
If we take 588 away from 667, we end up with 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 84

Let's proceed to step 6:
When dividing 798 by 84, we get 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 9879.0
Deduct 756 from 798 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
The number 84 fits into 420 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9879.5
If we take 420 away from 420, we end up 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.

Going ahead to step 8:
84 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9879.5
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.

On to step 9:
When dividing 0 by 84, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9879.5
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.

After the division, we end up with 9879.5 and a remainder of 0.0.
