4002 ÷ 72 
We want to figure out the number of times 4002 can be divided by 72.

Step 1:
If we divide 4 by 72, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 72

Let's proceed to step 2:
72 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 72

Moving on to step 3:
72 goes into 400 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 360 from 400, we get 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 72

Going ahead to step 4:
The number 72 fits into 402 5 times, leaving a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtract 360 from 402 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 5:
72 can be fit into 420 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 55.5
Subtract 360 from 420 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 6:
The number 72 fits into 600 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 55.58
Deduct 576 from 600 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
If we divide 240 by 72, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 55.583
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 55.5833
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 55.5833 with a remaining 0.00024.
