We're dividing 159160 by 72 
We want to figure out the number of times 159160 can be divided by 72.

Step 1:
72 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 72

Let's proceed to step 2:
72 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 72

Going ahead to step 3:
If we divide 159 by 72, we get 2 and a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 144 from 159 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 72

Going ahead to step 4:
When dividing 151 by 72, we get 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 144 from 151, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 72

On to step 5:
The number 72 fits into 76 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.0
If we subtract 72 from 76, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 72

Step 6:
The number 72 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2210.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
72 can be fit into 400 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 2210.5
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 72, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 2210.55
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 2210.55 with a remaining 0.04.
