72070825 divided by 15 
Let's see how many times 15 fits into 72070825.

Step 1:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 15

On to step 2:
The number 15 fits into 72 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 12 after subtracting 60 from 72.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 15

On to step 3:
15 can be fit into 120 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 120 away from 120, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 15

Advancing to step 4:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 15

Advancing to step 5:
15 goes into 70 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4804.0
If we subtract 60 from 70, we get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 15

Advancing to step 6:
108 divided by 15 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 48047.0
The remainder is 3 after subtracting 105 from 108.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 15

Let's proceed to step 7:
15 can be fit into 32 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 480472.0
Subtracting 30 from 32 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 15

Moving on to step 8:
15 goes into 25 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 4804721.0
If we subtract 15 from 25, 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.

Let's proceed to step 9:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 4804721.6
If we take 90 away from 100, we end up 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 10:
100 divided by 15 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4804721.66
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 4804721.66 and a remainder of 0.01.
