We look at the division of 307286 by 71 
Let's see how many times 71 fits into 307286.

Advancing to step 1:
71 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 71

Moving on to step 2:
When dividing 30 by 71, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 71

Advancing to step 3:
307 divided by 71 is 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 284 from 307 leaves us with 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 71

Advancing to step 4:
If we divide 232 by 71, we get 3 and a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 213 away from 232, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 71

Moving on to step 5:
71 goes into 198 2 times with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 432.0
The remainder is 56 after subtracting 142 from 198.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 71

Moving on to step 6:
71 can be fit into 566 7 times, resulting in a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 4327.0
The remainder is 69 after subtracting 497 from 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
The number 71 fits into 690 9 times, leaving a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 4327.9
If we take 639 away from 690, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 8:
If we divide 510 by 71, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 4327.97
If we take 497 away from 510, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
The number 71 fits into 130 1 times, leaving a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 4327.971
If we take 71 away from 130, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
590 divided by 71 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 4327.9718
Subtract 568 from 590 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
When dividing 220 by 71, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 4327.97183
Deduct 213 from 220 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
The number 71 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 4327.97183
Subtracting 0 from 70 leaves us 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 13:
71 goes into 700 9 times with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 4327.9718309
The remainder is 61 after subtracting 639 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 14:
The number 71 fits into 610 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 4327.97183098
Subtracting 568 from 610 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 4327.97183098 and a remainder of 4.2e-08.
