We look at the division of 50391 by 71 
We want to divide 50391 by 71.

Step 1:
If we divide 5 by 71, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 71

Let's proceed to step 2:
71 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 71

Advancing to step 3:
503 divided by 71 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 6 after subtracting 497 from 503.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 71

Let's proceed to step 4:
69 divided by 71 is 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 70.0
Deduct 0 from 69 and we're left with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 71

On to step 5:
The number 71 fits into 691 9 times, leaving a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 709.0
If we subtract 639 from 691, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 6:
71 goes into 520 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 709.7
Deduct 497 from 520 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 71 fits into 230 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 709.73
The remainder is 17 after subtracting 213 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
If we divide 170 by 71, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 709.732
If we subtract 142 from 170, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
71 can be fit into 280 3 times, resulting in a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 709.7323
Subtracting 213 from 280 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 10:
71 goes into 670 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 709.73239
If we take 639 away from 670, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
If we divide 310 by 71, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 709.732394
The remainder is 26 after subtracting 284 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
71 goes into 260 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 709.7323943
The remainder is 47 after subtracting 213 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
If we divide 470 by 71, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 709.73239436
If we subtract 426 from 470, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 709.73239436 with a remainder of 4.4e-08.
