We're dividing 303924 by 72 
We want to divide 303924 by 72.

Going ahead to 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
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 72

Going ahead to step 2:
72 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 72

Moving on to step 3:
If we divide 303 by 72, we get 4 and a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 288 from 303, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 72

Going ahead to step 4:
72 can be fit into 159 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 144 away from 159, we end up with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 72

Going ahead to step 5:
152 divided by 72 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 422.0
Subtracting 144 from 152 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 72

Moving on to step 6:
The number 72 fits into 84 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 4221.0
Subtracting 72 from 84 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
When dividing 120 by 72, we get 1 with a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 4221.1
Subtract 72 from 120 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
If we divide 480 by 72, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 4221.16
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 72, we get 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 4221.166
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 4221.166 with a remaining 0.0048.
