310884 ÷ 85 
Let's see how many times 85 fits into 310884.

On to step 1:
3 divided by 85 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 85

Advancing to step 2:
The number 85 fits into 31 0 times, leaving a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 85

Let's proceed to step 3:
When dividing 310 by 85, we get 3 with a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 255 from 310 and we're left with 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 85

Step 4:
When dividing 558 by 85, we get 6 with a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 48 after subtracting 510 from 558.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 85

Step 5:
The number 85 fits into 488 5 times, leaving a remainder of 63.
The next digit of our result is 5. 
Result so far: 365.0
The remainder is 63 after subtracting 425 from 488.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 85

On to step 6:
When dividing 634 by 85, we get 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 3657.0
Subtract 595 from 634 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.

Going ahead to step 7:
The number 85 fits into 390 4 times, leaving a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 3657.4
Subtract 340 from 390 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 3657.45
If we take 425 away from 500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 3657.458
If we take 680 away from 750, 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.

Step 10:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 3657.4588
If we subtract 680 from 700, we 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.

Our division results in 3657.4588 with a remaining 0.0002.
