We divide 27989 by 86
We want to divide 27989 by 86.

On to step 1:
When dividing 2 by 86, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 86

Moving on to step 2:
When dividing 27 by 86, we get 0 with a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 86

Advancing to step 3:
If we divide 279 by 86, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 258 from 279, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 86

Step 4:
If we divide 218 by 86, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 172 from 218 to get 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 86

Going ahead to step 5:
86 goes into 469 5 times with a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 325.0
Subtract 430 from 469 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 6:
86 goes into 390 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 325.4
The remainder is 46 after subtracting 344 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
When dividing 460 by 86, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 325.45
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
86 goes into 300 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 325.453
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
The number 86 fits into 420 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 325.4534
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
If we divide 760 by 86, we get 8 and a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 325.45348
Subtract 688 from 760 to get 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:
If we divide 720 by 86, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 325.453488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 325.453488, and the remainder is 3.2e-06.
