12515 divided by 72 
We want to figure out the number of times 12515 can be divided by 72.

Advancing to step 1:
The number 72 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 72

Going ahead to step 2:
If we divide 12 by 72, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 72

Going ahead to step 3:
72 can be fit into 125 1 times, resulting in a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 72 from 125 leaves us with 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 72

On to step 4:
72 can be fit into 531 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 504 away from 531, we end up with 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 72

Step 5:
When dividing 275 by 72, we get 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtracting 216 from 275 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 6:
When dividing 590 by 72, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 173.8
Subtract 576 from 590 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 72 is 1 with a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 173.81
If we take 72 away from 140, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
680 divided by 72 is 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 173.819
Subtract 648 from 680 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
320 divided by 72 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 173.8194
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
If we divide 320 by 72, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 173.81944
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 173.81944 and a remainder of 3.2e-05.
