We look at the division of 28687 by 84 
Let's see how many times 84 fits into 28687.

Moving on to step 1:
84 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 84

Moving on to step 2:
28 divided by 84 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 84

On to step 3:
When dividing 286 by 84, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 252 from 286 and we're left with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 84

On to step 4:
If we divide 348 by 84, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 336 from 348 and we're left with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 84

Step 5:
The number 84 fits into 127 1 times, leaving a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 341.0
If we take 84 away from 127, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 6:
If we divide 430 by 84, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 341.5
The remainder is 10 after subtracting 420 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
When dividing 100 by 84, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 341.51
Deduct 84 from 100 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.

On to step 8:
When dividing 160 by 84, we get 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 341.511
If we subtract 84 from 160, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 341.511 with a remaining 0.0076.
