We look at the division of 399391 by 14 
We want to figure out the number of times 399391 can be divided by 14.

Going ahead to step 1:
The number 14 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 14

Step 2:
When dividing 39 by 14, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 28 from 39 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 14

Advancing to step 3:
When dividing 119 by 14, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 112 from 119 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 14

Let's proceed to step 4:
14 goes into 73 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 285.0
Deduct 70 from 73 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 14

Advancing to step 5:
The number 14 fits into 39 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2852.0
Subtracting 28 from 39 leaves us with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 14

On to step 6:
The number 14 fits into 111 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 28527.0
The remainder is 13 after subtracting 98 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
14 can be fit into 130 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 28527.9
Subtract 126 from 130 to get 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 8:
The number 14 fits into 40 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 28527.92
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 9:
If we divide 120 by 14, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 28527.928
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
14 can be fit into 80 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 28527.9285
Subtracting 70 from 80 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
When dividing 100 by 14, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 28527.92857
Deduct 98 from 100 and we're left 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.

Let's proceed to step 12:
The number 14 fits into 20 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 28527.928571
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
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: 28527.9285714
Deduct 56 from 60 and we're left 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.

Let's proceed to step 14:
40 divided by 14 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 28527.92857142
The remainder is 12 after subtracting 28 from 40.
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 28527.92857142 with a balance of 1.2e-08.
