We divide 871863 by 84
Our goal is to divide 871863 by 84.

Moving on to step 1:
84 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 84

Step 2:
84 goes into 87 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 84 from 87 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 84

Let's proceed to step 3:
84 goes into 31 0 times with a remainder of 31.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 31, we end up with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 84

Let's proceed to step 4:
If we divide 318 by 84, we get 3 and a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Deduct 252 from 318 and we're left with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 84

Moving on to step 5:
When dividing 666 by 84, we get 7 with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 1037.0
If we take 588 away from 666, we end up with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 84

On to step 6:
If we divide 783 by 84, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 10379.0
If we subtract 756 from 783, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
If we divide 270 by 84, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 10379.3
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
When dividing 180 by 84, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 10379.32
If we take 168 away from 180, we end up 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.

Moving on to step 9:
120 divided by 84 is 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 10379.321
Subtract 84 from 120 to 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.

Going ahead to step 10:
84 goes into 360 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 10379.3214
Subtracting 336 from 360 leaves us 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.

On to step 11:
84 can be fit into 240 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 10379.32142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
720 divided by 84 is 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 10379.321428
Subtracting 672 from 720 leaves us 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 13:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 10379.3214285
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.

Step 14:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 10379.32142857
Deduct 588 from 600 and we're left 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.

Our division results in 10379.32142857 with a remaining 1.2e-08.
