The number 395 fits into 782 1 times, leaving a remainder of 387.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 387 after subtracting 395 from 782.
Fetch the next digit (1) from the dividend, attach it to 387 and continue: 3871 / 395

On to step 4:
395 goes into 3871 9 times with a remainder of 316.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 3555 from 3871 and we're left with 316.
Bring next digit (2) of the dividend behind the 316 and repeat the process: 3162 / 395

Going ahead to step 5:
3162 divided by 395 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 198.0
If we take 3160 away from 3162, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 395

Moving on to step 6:
395 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 1980.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 395

Going ahead to step 7:
395 goes into 288 0 times with a remainder of 288.
Record the quotient 0 as the next digit in the result. 
Result so far: 19800.0
Subtract 0 from 288 to get 288.
Take the next digit (9) from the dividend and append it to 288, then repeat: 2889 / 395

On to step 8:
395 goes into 2889 7 times with a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 198007.0
Subtracting 2765 from 2889 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 9:
395 can be fit into 1240 3 times, resulting in a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 198007.3
Subtracting 1185 from 1240 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
550 divided by 395 is 1 with a remainder of 155.
Use 1 as the next digit of our solution. 
Result so far: 198007.31
If we subtract 395 from 550, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 11:
1550 divided by 395 is 3 with a remainder of 365.
The number 3 becomes the next digit in our result. 
Result so far: 198007.313
Deduct 1185 from 1550 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 12:
When dividing 3650 by 395, we get 9 with a remainder of 95.
Put 9 as the next digit of the answer. 
Result so far: 198007.3139
The remainder is 95 after subtracting 3555 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 13:
The number 395 fits into 950 2 times, leaving a remainder of 160.
The next digit of our result is 2. 
Result so far: 198007.31392
Subtracting 790 from 950 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
When dividing 1600 by 395, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 198007.313924
Subtracting 1580 from 1600 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 15:
395 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 198007.313924
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
When dividing 2000 by 395, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 198007.31392405
Deduct 1975 from 2000 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 198007.31392405 with a remaining 2.5e-08.
