We divide 159928 by 72
We want to figure out the number of times 159928 can be divided by 72.

Step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 72

On to step 2:
15 divided by 72 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 72

Going ahead to step 3:
The number 72 fits into 159 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 144 from 159 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 72

Moving on to step 4:
If we divide 159 by 72, we get 2 and a remainder of 15.
The next digit of our result is 2. 
Result so far: 22.0
If we take 144 away from 159, we end up with 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 72

Advancing to step 5:
72 goes into 152 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 222.0
Subtract 144 from 152 to get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 72

Moving on to step 6:
If we divide 88 by 72, we get 1 and a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 2221.0
Subtract 72 from 88 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2221.2
Subtract 144 from 160 to get 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 8:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2221.22
Subtracting 144 from 160 leaves us 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.

After the division, we end up with 2221.22 and a remainder of 0.016.
