Let's divide 3939649 by 395
We want to divide 3939649 by 395.

On to step 1:
When dividing 3 by 395, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 395

Going ahead to step 2:
If we divide 39 by 395, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (3) from the dividend and append it to 39, then repeat: 393 / 395

On to step 3:
395 can be fit into 393 0 times, resulting in a remainder of 393.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 393 after subtracting 0 from 393.
Fetch the next digit (9) from the dividend, attach it to 393 and continue: 3939 / 395

Step 4:
When dividing 3939 by 395, we get 9 with a remainder of 384.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 3555 from 3939, we get 384.
Bring next digit (6) of the dividend behind the 384 and repeat the process: 3846 / 395

Going ahead to step 5:
395 goes into 3846 9 times with a remainder of 291.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 3555 from 3846 leaves us with 291.
Bring next digit (4) of the dividend behind the 291 and repeat the process: 2914 / 395

Step 6:
If we divide 2914 by 395, we get 7 and a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 997.0
If we subtract 2765 from 2914, we get 149.
Fetch the next digit (9) from the dividend, attach it to 149 and continue: 1499 / 395

Let's proceed to step 7:
When dividing 1499 by 395, we get 3 with a remainder of 314.
Record the quotient 3 as the next digit in the result. 
Result so far: 9973.0
Deduct 1185 from 1499 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 8:
3140 divided by 395 is 7 with a remainder of 375.
The next digit of our result is 7. 
Result so far: 9973.7
The remainder is 375 after subtracting 2765 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 9:
When dividing 3750 by 395, we get 9 with a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 9973.79
Subtract 3555 from 3750 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 10:
395 goes into 1950 4 times with a remainder of 370.
Write down 4 as next digit of the result. 
Result so far: 9973.794
Deduct 1580 from 1950 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 11:
395 goes into 3700 9 times with a remainder of 145.
Write down 9 as next digit of the result. 
Result so far: 9973.7949
If we subtract 3555 from 3700, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 12:
The number 395 fits into 1450 3 times, leaving a remainder of 265.
The next digit of our result is 3. 
Result so far: 9973.79493
Subtracting 1185 from 1450 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 13:
If we divide 2650 by 395, we get 6 and a remainder of 280.
Put 6 as the next digit of the answer. 
Result so far: 9973.794936
The remainder is 280 after subtracting 2370 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 14:
The number 395 fits into 2800 7 times, leaving a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 9973.7949367
Subtract 2765 from 2800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 15:
The number 395 fits into 350 0 times, leaving a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 9973.7949367
Subtract 0 from 350 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 9973.7949367, with a leftover of 3.5e-07.
