We look at the division of 640349 by 14 
Our goal is to divide 640349 by 14.

Advancing to step 1:
If we divide 6 by 14, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 14

Step 2:
64 divided by 14 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 56 from 64, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 14

Moving on to step 3:
If we divide 80 by 14, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
The remainder is 10 after subtracting 70 from 80.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 14

Step 4:
The number 14 fits into 103 7 times, leaving a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 457.0
Subtract 98 from 103 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 14

Moving on to step 5:
54 divided by 14 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 4573.0
Deduct 42 from 54 and we're left with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 14

Let's proceed to step 6:
When dividing 129 by 14, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 45739.0
Subtracting 126 from 129 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
14 goes into 30 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 45739.2
The remainder is 2 after subtracting 28 from 30.
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 8:
14 can be fit into 20 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 45739.21
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.

On to step 9:
14 goes into 60 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 45739.214
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.

Step 10:
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: 45739.2142
If we subtract 28 from 40, we get 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 11:
When dividing 120 by 14, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 45739.21428
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 14, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 45739.214285
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.

Let's proceed to step 13:
If we divide 100 by 14, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 45739.2142857
Subtracting 98 from 100 leaves us 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.

Moving on to step 14:
14 goes into 20 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 45739.21428571
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.

Our division results in 45739.21428571 with a remaining 6e-09.
