We look at the division of 86087 by 28 
We want to divide 86087 by 28.

Let's proceed to step 1:
The number 28 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 28

Moving on to step 2:
If we divide 86 by 28, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 84 from 86 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 28

Going ahead to step 3:
When dividing 20 by 28, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 28

On to step 4:
When dividing 208 by 28, we get 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 307.0
The remainder is 12 after subtracting 196 from 208.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 28

Advancing to step 5:
When dividing 127 by 28, we get 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 3074.0
If we subtract 112 from 127, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 6:
The number 28 fits into 150 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3074.5
Deduct 140 from 150 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 28, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 3074.53
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.

Going ahead to step 8:
When dividing 160 by 28, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 3074.535
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
28 goes into 200 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 3074.5357
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 3074.53571
Deduct 28 from 40 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 11:
When dividing 120 by 28, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 3074.535714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 28, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 3074.5357142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 3074.53571428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 3074.53571428, with a leftover of 1.6e-08.
