We look at the division of 23101427 by 15 
We want to figure out the number of times 23101427 can be divided by 15.

Moving on to step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 15

Let's proceed to step 2:
When dividing 23 by 15, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 15 from 23.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 15

Step 3:
15 goes into 81 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 75 from 81 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 15

Step 4:
If we divide 60 by 15, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 154.0
Subtract 60 from 60 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 15

Let's proceed to step 5:
The number 15 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 1540.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 15

Moving on to step 6:
15 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 15400.0
If we take 0 away from 14, we end up with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 15

Step 7:
15 can be fit into 142 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 154009.0
Deduct 135 from 142 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 15

Advancing to step 8:
15 goes into 77 5 times with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 1540095.0
Subtract 75 from 77 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 15 fits into 20 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 1540095.1
Subtracting 15 from 20 leaves us with 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 10:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 1540095.13
If we take 45 away from 50, we end up with 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 11:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1540095.133
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.

The final result is 1540095.133 with a remainder of 0.0005.
