We're dividing 878452 by 84 
We want to figure out the number of times 878452 can be divided by 84.

Moving on to step 1:
84 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 84

Advancing to step 2:
The number 84 fits into 87 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 84 from 87 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 84

Moving on to step 3:
84 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 84

On to step 4:
384 divided by 84 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 336 from 384 and we're left with 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 84

Going ahead to step 5:
84 can be fit into 485 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 1045.0
Deduct 420 from 485 and we're left with 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 84

On to step 6:
If we divide 652 by 84, we get 7 and a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 10457.0
The remainder is 64 after subtracting 588 from 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
If we divide 640 by 84, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 10457.7
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 8:
84 can be fit into 520 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 10457.76
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
If we divide 160 by 84, we get 1 and a remainder of 76.
The next digit of our result is 1. 
Result so far: 10457.761
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
If we divide 760 by 84, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 10457.7619
The remainder is 4 after subtracting 756 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
40 divided by 84 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10457.7619
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
The number 84 fits into 400 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 10457.761904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
If we divide 640 by 84, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 10457.7619047
Subtract 588 from 640 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
520 divided by 84 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 10457.76190476
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 10457.76190476 with a remaining 1.6e-08.
