We divide 17158565 by 387
Let's see how many times 387 fits into 17158565.

Going ahead to step 1:
387 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 387

On to step 2:
The number 387 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 387

Moving on to step 3:
387 goes into 171 0 times with a remainder of 171.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 171 after subtracting 0 from 171.
Append the next digit (5) from the dividend to 171 and continue with: 1715 / 387

On to step 4:
If we divide 1715 by 387, we get 4 and a remainder of 167.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1548 away from 1715, we end up with 167.
Fetch the next digit (8) from the dividend, attach it to 167 and continue: 1678 / 387

Step 5:
The number 387 fits into 1678 4 times, leaving a remainder of 130.
The next digit of our result is 4. 
Result so far: 44.0
Subtracting 1548 from 1678 leaves us with 130.
Fetch the next digit (5) from the dividend, attach it to 130 and continue: 1305 / 387

Let's proceed to step 6:
1305 divided by 387 is 3 with a remainder of 144.
Record the quotient 3 as the next digit in the result. 
Result so far: 443.0
If we take 1161 away from 1305, we end up with 144.
Take the next digit (6) from the dividend and append it to 144, then repeat: 1446 / 387

On to step 7:
387 goes into 1446 3 times with a remainder of 285.
Use 3 as the next digit of our solution. 
Result so far: 4433.0
The remainder is 285 after subtracting 1161 from 1446.
Take the next digit (5) from the dividend and append it to 285, then repeat: 2855 / 387

Moving on to step 8:
387 goes into 2855 7 times with a remainder of 146.
The number 7 becomes the next digit in our result. 
Result so far: 44337.0
Subtracting 2709 from 2855 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 9:
387 can be fit into 1460 3 times, resulting in a remainder of 299.
The next digit of our result is 3. 
Result so far: 44337.3
The remainder is 299 after subtracting 1161 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 10:
2990 divided by 387 is 7 with a remainder of 281.
Use 7 as the next digit of our solution. 
Result so far: 44337.37
Subtract 2709 from 2990 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 11:
2810 divided by 387 is 7 with a remainder of 101.
Use 7 as the next digit of our solution. 
Result so far: 44337.377
If we take 2709 away from 2810, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final outcome is 44337.377, with a leftover of 0.0101.
