644568 divided by 14 
Our goal is to divide 644568 by 14.

Step 1:
If we divide 6 by 14, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 14

Let's proceed to step 2:
14 can be fit into 64 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 56 from 64, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 14

Advancing to step 3:
The number 14 fits into 84 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
The remainder is 0 after subtracting 84 from 84.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 14

Advancing to step 4:
If we divide 5 by 14, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 460.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 14

Going ahead to step 5:
If we divide 56 by 14, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4604.0
The remainder is 0 after subtracting 56 from 56.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 14

Moving on to step 6:
The number 14 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 46040.0
The remainder is 8 after subtracting 0 from 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 7:
If we divide 80 by 14, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 46040.5
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.

Step 8:
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: 46040.57
If we subtract 98 from 100, we get 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 9:
14 goes into 20 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 46040.571
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 10:
The number 14 fits into 60 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 46040.5714
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.

Advancing to step 11:
40 divided by 14 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 46040.57142
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 12:
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: 46040.571428
If we subtract 112 from 120, we 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.

Let's proceed to step 13:
If we divide 80 by 14, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 46040.5714285
Subtract 70 from 80 to 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 14:
When dividing 100 by 14, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 46040.57142857
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.

The final result is 46040.57142857 with a remainder of 2e-09.
