We look at the division of 391783 by 71 
Let's see how many times 71 fits into 391783.

Advancing to step 1:
71 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 71

Let's proceed to step 2:
If we divide 39 by 71, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 71

Moving on to step 3:
If we divide 391 by 71, we get 5 and a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 355 from 391 to get 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 71

On to step 4:
71 goes into 367 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 355 from 367 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 71

Step 5:
71 can be fit into 128 1 times, resulting in a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 551.0
Subtract 71 from 128 to get 57.
Take the next digit (3) from the dividend and append it to 57, then repeat: 573 / 71

On to step 6:
The number 71 fits into 573 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 5518.0
If we take 568 away from 573, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 71 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 5518.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
71 goes into 500 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 5518.07
Subtracting 497 from 500 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
The number 71 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5518.07
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
The number 71 fits into 300 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 5518.0704
Deduct 284 from 300 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 71 fits into 160 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 5518.07042
The remainder is 18 after subtracting 142 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
When dividing 180 by 71, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 5518.070422
Subtracting 142 from 180 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 5518.070422 with a remainder of 3.8e-06.
