We're dividing 39640 by 14 
We're looking to find how many times 14 goes into 39640.

On to step 1:
14 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 14

On to step 2:
14 goes into 39 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 28 away from 39, we end up with 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 14

Going ahead to step 3:
14 can be fit into 116 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 112 from 116 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 14

Moving on to step 4:
44 divided by 14 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 283.0
Subtract 42 from 44 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 14

Step 5:
14 goes into 20 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 2831.0
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
When dividing 60 by 14, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2831.4
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 14, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2831.42
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 14, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 2831.428
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
14 can be fit into 80 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2831.4285
If we subtract 70 from 80, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
14 goes into 100 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 2831.42857
If we take 98 away from 100, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
If we divide 20 by 14, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 2831.428571
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 2831.4285714
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
40 divided by 14 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2831.42857142
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 2831.42857142 with a balance of 1.2e-08.
