Let's divide 86571 by 28
Let's see how many times 28 fits into 86571.

Let's proceed to step 1:
The number 28 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 28

Let's proceed to step 2:
86 divided by 28 is 3 with 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.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 28

Advancing to step 3:
28 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 28

Going ahead to step 4:
28 goes into 257 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 309.0
If we take 252 away from 257, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 28

On to step 5:
28 goes into 51 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 3091.0
Deduct 28 from 51 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 6:
28 can be fit into 230 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 3091.8
If we subtract 224 from 230, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
28 goes into 60 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 3091.82
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 3091.821
If we subtract 28 from 40, we get 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:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3091.8214
Subtracting 112 from 120 leaves us 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 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 3091.82142
If we take 56 away from 80, we end up 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.

Moving on to step 11:
If we divide 240 by 28, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 3091.821428
If we take 224 away from 240, we end up 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 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 3091.8214285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 3091.82142857
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 3091.82142857 with a balance of 4e-09.
