We divide 312602 by 86
We're looking to find how many times 86 goes into 312602.

Moving on to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 86

Moving on to step 2:
86 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 86

Step 3:
If we divide 312 by 86, we get 3 and a remainder of 54.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 258 from 312 leaves us with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 86

Let's proceed to step 4:
546 divided by 86 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
Subtract 516 from 546 to get 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 86

On to step 5:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The next digit of our result is 3. 
Result so far: 363.0
The remainder is 42 after subtracting 258 from 300.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 86

Moving on to step 6:
The number 86 fits into 422 4 times, leaving a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 3634.0
Subtract 344 from 422 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 7:
The number 86 fits into 780 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 3634.9
Deduct 774 from 780 and we're left with 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 8:
86 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3634.9
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
86 goes into 600 6 times with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 3634.906
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
840 divided by 86 is 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 3634.9069
Subtracting 774 from 840 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
The number 86 fits into 660 7 times, leaving a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 3634.90697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
If we divide 580 by 86, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 3634.906976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
When dividing 640 by 86, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 3634.9069767
Subtracting 602 from 640 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
If we divide 380 by 86, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 3634.90697674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 3634.90697674 and a remainder of 3.6e-08.
