We divide 315083 by 86
Let's see how many times 86 fits into 315083.

Moving on to step 1:
3 divided by 86 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 86

On to step 2:
The number 86 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.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 86

Let's proceed to step 3:
If we divide 315 by 86, we get 3 and a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 57 after subtracting 258 from 315.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 86

Advancing to step 4:
If we divide 570 by 86, we get 6 and a remainder of 54.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 516 from 570 and we're left with 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 86

Advancing to step 5:
548 divided by 86 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 366.0
Deduct 516 from 548 and we're left with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 86

On to step 6:
The number 86 fits into 323 3 times, leaving a remainder of 65.
Write down 3 as next digit of the result. 
Result so far: 3663.0
If we take 258 away from 323, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
86 goes into 650 7 times with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 3663.7
Subtracting 602 from 650 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
If we divide 480 by 86, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3663.75
Deduct 430 from 480 and we're left 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.

Going ahead to step 9:
86 goes into 500 5 times with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 3663.755
Deduct 430 from 500 and we're left 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.

Our division results in 3663.755 with a remaining 0.007.
