316186 divided by 86 
Our goal is to divide 316186 by 86.

Step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 86

Advancing to step 2:
86 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 86

On to step 3:
316 divided by 86 is 3 with a remainder of 58.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 258 from 316, we get 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 86

Moving on to step 4:
86 goes into 581 6 times with a remainder of 65.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we subtract 516 from 581, we get 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 86

On to step 5:
86 goes into 658 7 times with a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 367.0
Deduct 602 from 658 and we're left with 56.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 86

Let's proceed to step 6:
86 can be fit into 566 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 3676.0
Subtracting 516 from 566 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
500 divided by 86 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 3676.5
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
When dividing 700 by 86, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3676.58
Subtracting 688 from 700 leaves us 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.

On to step 9:
86 can be fit into 120 1 times, resulting in a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 3676.581
Deduct 86 from 120 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
86 goes into 340 3 times with a remainder of 82.
The next digit of our result is 3. 
Result so far: 3676.5813
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 11:
If we divide 820 by 86, we get 9 and a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 3676.58139
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 12:
The number 86 fits into 460 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3676.581395
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.

Let's proceed to step 13:
86 goes into 300 3 times with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 3676.5813953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 14:
86 goes into 420 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 3676.58139534
Subtract 344 from 420 to 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.

The final outcome is 3676.58139534, with a leftover of 7.6e-08.
