We look at the division of 581373 by 4 
Let's see how many times 4 fits into 581373.

Advancing to step 1:
The number 4 fits into 5 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 5 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 4

Advancing to step 2:
4 goes into 18 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 2 after subtracting 16 from 18.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

Going ahead to step 3:
When dividing 21 by 4, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtract 20 from 21 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 4

Let's proceed to step 4:
When dividing 13 by 4, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1453.0
The remainder is 1 after subtracting 12 from 13.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 4

Let's proceed to step 5:
4 can be fit into 17 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 14534.0
If we take 16 away from 17, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Going ahead to step 6:
4 goes into 13 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 145343.0
Subtracting 12 from 13 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 4, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 145343.2
Deduct 8 from 10 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.

Moving on to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 145343.25
If we subtract 20 from 20, 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 9:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 145343.25
If we take 0 away from 0, we end up 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.

Step 10:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 145343.25
Subtracting 0 from 0 leaves us 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 quotient of the division is 145343.25, and the remainder is 0.0.
