280996 ÷ 72 
Our goal is to divide 280996 by 72.

Step 1:
If we divide 2 by 72, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 72

Going ahead to step 2:
28 divided by 72 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 72

Going ahead to step 3:
280 divided by 72 is 3 with a remainder of 64.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 216 from 280 to get 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 72

Advancing to step 4:
72 can be fit into 649 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 648 from 649 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 72

Advancing to step 5:
The number 72 fits into 19 0 times, leaving a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 390.0
Subtract 0 from 19 to get 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 72

Advancing to step 6:
72 can be fit into 196 2 times, resulting in a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 3902.0
If we take 144 away from 196, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
The number 72 fits into 520 7 times, leaving a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 3902.7
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
72 goes into 160 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 3902.72
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 3902.722
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 3902.722 with a remaining 0.0016.
