We look at the division of 303544 by 72 
Let's see how many times 72 fits into 303544.

Step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 72

On to step 2:
When dividing 30 by 72, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 72

Going ahead to step 3:
If we divide 303 by 72, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 288 from 303, we get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 72

Let's proceed to step 4:
The number 72 fits into 155 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 144 from 155 and we're left with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 72

Moving on to step 5:
72 can be fit into 114 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
The remainder is 42 after subtracting 72 from 114.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 72

Advancing to step 6:
72 goes into 424 5 times with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 4215.0
If we take 360 away from 424, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
The number 72 fits into 640 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 4215.8
Subtract 576 from 640 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
If we divide 640 by 72, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 4215.88
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 4215.88 and a remainder of 0.064.
