We look at the division of 878475 by 84 
Let's see how many times 84 fits into 878475.

On to step 1:
The number 84 fits into 8 0 times, leaving 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.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 84

Let's proceed to step 2:
87 divided by 84 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 84 from 87, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 84

Moving on to step 3:
When dividing 38 by 84, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 84

Step 4:
If we divide 384 by 84, we get 4 and a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 336 from 384 and we're left with 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 84

Going ahead to step 5:
84 can be fit into 487 5 times, resulting in a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 1045.0
If we subtract 420 from 487, we get 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 84

On to step 6:
84 goes into 675 8 times with a remainder of 3.
The next digit of our result is 8. 
Result so far: 10458.0
Subtracting 672 from 675 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 84, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 10458.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
84 goes into 300 3 times with a remainder of 48.
The next digit of our result is 3. 
Result so far: 10458.03
If we take 252 away from 300, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
If we divide 480 by 84, we get 5 and a remainder of 60.
The next digit of our result is 5. 
Result so far: 10458.035
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
84 goes into 600 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 10458.0357
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
When dividing 120 by 84, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 10458.03571
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
When dividing 360 by 84, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 10458.035714
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
When dividing 240 by 84, we get 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 10458.0357142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
720 divided by 84 is 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 10458.03571428
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 10458.03571428 with a remainder of 4.8e-08.
