639319 ÷ 14 
Our goal is to divide 639319 by 14.

Step 1:
The number 14 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 14

Moving on to step 2:
63 divided by 14 is 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 56 away from 63, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 14

Advancing to step 3:
79 divided by 14 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 70 from 79 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 14

Let's proceed to step 4:
93 divided by 14 is 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 456.0
Subtracting 84 from 93 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 14

Going ahead to step 5:
14 can be fit into 91 6 times, resulting in a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 4566.0
If we take 84 away from 91, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 14

Advancing to step 6:
If we divide 79 by 14, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 45665.0
Subtract 70 from 79 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 14 fits into 90 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 45665.6
Deduct 84 from 90 and we're left 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.

Moving on to step 8:
The number 14 fits into 60 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 45665.64
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 9:
The number 14 fits into 40 2 times, leaving a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 45665.642
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.

Moving on to step 10:
14 can be fit into 120 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 45665.6428
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.

On to step 11:
14 can be fit into 80 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 45665.64285
The remainder is 10 after subtracting 70 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
If we divide 100 by 14, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 45665.642857
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.

Advancing to step 13:
20 divided by 14 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 45665.6428571
If we take 14 away from 20, we end up 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.

Let's proceed to step 14:
14 can be fit into 60 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 45665.64285714
If we subtract 56 from 60, we 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.

Our division results in 45665.64285714 with a remaining 4e-09.
