We're dividing 72141 by 15 
Let's see how many times 15 fits into 72141.

Advancing to step 1:
7 divided by 15 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 15

Step 2:
The number 15 fits into 72 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 60 from 72 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 15

On to step 3:
When dividing 121 by 15, we get 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 120 from 121 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 15

Moving on to step 4:
15 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 480.0
If we take 0 away from 14, we end up with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 15

Step 5:
If we divide 141 by 15, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 4809.0
Subtract 135 from 141 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
The number 15 fits into 60 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4809.4
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4809.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 15 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4809.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4809.4 with a remaining 0.0.
