We look at the division of 863916 by 84 
We're looking to find how many times 84 goes into 863916.

Let's proceed to step 1:
If we divide 8 by 84, we get 0 and 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 (6) from the dividend after 8, then repeat: 86 / 84

Step 2:
The number 84 fits into 86 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 84 from 86.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 84

Step 3:
When dividing 23 by 84, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 23 after subtracting 0 from 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 84

Moving on to step 4:
239 divided by 84 is 2 with a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtract 168 from 239 to get 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 84

On to step 5:
If we divide 711 by 84, we get 8 and a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 1028.0
If we take 672 away from 711, we end up with 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 84

Going ahead to step 6:
The number 84 fits into 396 4 times, leaving a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 10284.0
The remainder is 60 after subtracting 336 from 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
600 divided by 84 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 10284.7
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.

Moving on to step 8:
84 goes into 120 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 10284.71
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
360 divided by 84 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 10284.714
Subtract 336 from 360 to get 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 10:
If we divide 240 by 84, we get 2 and a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 10284.7142
Deduct 168 from 240 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
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: 10284.71428
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.

Advancing to step 12:
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: 10284.714285
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
If we divide 600 by 84, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 10284.7142857
If we take 588 away from 600, 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.

Going ahead to step 14:
120 divided by 84 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 10284.71428571
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 10284.71428571 with a remainder of 3.6e-08.
