We're dividing 30508 by 86 
Our goal is to divide 30508 by 86.

Let's proceed to step 1:
When dividing 3 by 86, we get 0 with 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.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 86

Let's proceed to step 2:
30 divided by 86 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 86

On to step 3:
The number 86 fits into 305 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 258 from 305 leaves us with 47.
Include the next digit (0) from the dividend after 47, then repeat: 470 / 86

Moving on to step 4:
If we divide 470 by 86, we get 5 and a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 430 from 470 and we're left with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 86

Going ahead to step 5:
86 can be fit into 408 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 354.0
If we take 344 away from 408, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 6:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 354.7
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
86 goes into 380 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 354.74
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 354.744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 354.744 with a remainder of 0.0016.
