We're dividing 390102 by 71 
Our goal is to divide 390102 by 71.

Advancing to step 1:
71 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 71

Step 2:
71 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 71

Going ahead to step 3:
71 can be fit into 390 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 355 away from 390, we end up with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 71

On to step 4:
71 can be fit into 351 4 times, resulting in a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we take 284 away from 351, we end up with 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 71

Step 5:
The number 71 fits into 670 9 times, leaving a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 549.0
The remainder is 31 after subtracting 639 from 670.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 71

Moving on to step 6:
71 goes into 312 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 5494.0
The remainder is 28 after subtracting 284 from 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
The number 71 fits into 280 3 times, leaving a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 5494.3
The remainder is 67 after subtracting 213 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 8:
71 goes into 670 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 5494.39
Deduct 639 from 670 and we're left 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.

Advancing to step 9:
The number 71 fits into 310 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 5494.394
If we subtract 284 from 310, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
71 can be fit into 260 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 5494.3943
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.

Going ahead to step 11:
If we divide 470 by 71, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 5494.39436
The remainder is 44 after subtracting 426 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
When dividing 440 by 71, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 5494.394366
Subtract 426 from 440 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 5494.394366, with a leftover of 1.4e-06.
