We're dividing 72784528 by 15 
Our goal is to divide 72784528 by 15.

On to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 15

Going ahead to step 2:
15 goes into 72 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 60 from 72, we get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 15

Let's proceed to step 3:
15 can be fit into 127 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 48.0
Subtract 120 from 127 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 15

Going ahead to step 4:
15 goes into 78 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 485.0
If we take 75 away from 78, we end up with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 15

Step 5:
34 divided by 15 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 4852.0
Subtract 30 from 34 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 15

On to step 6:
15 can be fit into 45 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 48523.0
If we take 45 away from 45, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 15

Step 7:
15 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 485230.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 15

Step 8:
The number 15 fits into 28 1 times, leaving a remainder of 13.
The next digit of our result is 1. 
Result so far: 4852301.0
Deduct 15 from 28 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
15 can be fit into 130 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 4852301.8
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4852301.86
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4852301.866
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 4852301.866 and a remainder of 0.001.
