We divide 573319 by 4
Let's see how many times 4 fits into 573319.

On to step 1:
4 goes into 5 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 4 from 5.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 4

Going ahead to step 2:
When dividing 17 by 4, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 16 from 17 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Going ahead to step 3:
If we divide 13 by 4, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 143.0
If we take 12 away from 13, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 4

Advancing to step 4:
If we divide 13 by 4, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1433.0
If we take 12 away from 13, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 4

Advancing to step 5:
4 goes into 11 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 14332.0
Subtracting 8 from 11 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 4

Step 6:
39 divided by 4 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 143329.0
The remainder is 3 after subtracting 36 from 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 143329.7
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.

Let's proceed to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 143329.75
Deduct 20 from 20 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.

Advancing to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 143329.75
If we subtract 0 from 0, we 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.

Moving on to step 10:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 143329.75
Deduct 0 from 0 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.

The final result is 143329.75 with a remainder of 0.0.
