We look at the division of 578221 by 14 
We want to figure out the number of times 578221 can be divided by 14.

Advancing to step 1:
14 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 14

Moving on to step 2:
If we divide 57 by 14, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 56 from 57, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 14

Going ahead to step 3:
The number 14 fits into 18 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 14 from 18 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 14

On to step 4:
When dividing 42 by 14, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 413.0
The remainder is 0 after subtracting 42 from 42.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 14

Step 5:
14 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 4130.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 14

Step 6:
If we divide 21 by 14, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 41301.0
The remainder is 7 after subtracting 14 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
14 goes into 70 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 41301.5
Deduct 70 from 70 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 14 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 41301.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
14 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41301.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 41301.5 with a remainder of 0.0.
