Let's divide 12271505 by 15
We're looking to find how many times 15 goes into 12271505.

Let's proceed to step 1:
When dividing 1 by 15, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 15

Let's proceed to step 2:
15 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 15

Step 3:
If we divide 122 by 15, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 120 from 122 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 15

Step 4:
When dividing 27 by 15, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 15 away from 27, we end up with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 15

On to step 5:
When dividing 121 by 15, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 818.0
Deduct 120 from 121 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 15

On to step 6:
The number 15 fits into 15 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 8181.0
Subtracting 15 from 15 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 15

Moving on to step 7:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 81810.0
Subtracting 0 from 0 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 15

Let's proceed to step 8:
5 divided by 15 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 818100.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 818100.3
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 818100.33
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 818100.33 with a remaining 0.005.
