We divide 15660454 by 387
Our goal is to divide 15660454 by 387.

Let's proceed to step 1:
The number 387 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 387

On to step 2:
387 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 387

On to step 3:
The number 387 fits into 156 0 times, leaving a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 156 after subtracting 0 from 156.
Fetch the next digit (6) from the dividend, attach it to 156 and continue: 1566 / 387

Step 4:
The number 387 fits into 1566 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1548 from 1566, we get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 387

Going ahead to step 5:
387 goes into 180 0 times with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 180, we get 180.
Grab the next digit (4) from the dividend, add it to 180, then carry on: 1804 / 387

Moving on to step 6:
387 can be fit into 1804 4 times, resulting in a remainder of 256.
Put 4 as the next digit of the answer. 
Result so far: 404.0
Subtracting 1548 from 1804 leaves us with 256.
Bring next digit (5) of the dividend behind the 256 and repeat the process: 2565 / 387

Step 7:
387 goes into 2565 6 times with a remainder of 243.
Put 6 as the next digit of the answer. 
Result so far: 4046.0
The remainder is 243 after subtracting 2322 from 2565.
Include the next digit (4) from the dividend after 243, then repeat: 2434 / 387

Going ahead to step 8:
If we divide 2434 by 387, we get 6 and a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 40466.0
Subtract 2322 from 2434 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 9:
The number 387 fits into 1120 2 times, leaving a remainder of 346.
Write down 2 as next digit of the result. 
Result so far: 40466.2
The remainder is 346 after subtracting 774 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 10:
387 goes into 3460 8 times with a remainder of 364.
Use 8 as the next digit of our solution. 
Result so far: 40466.28
Subtract 3096 from 3460 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 11:
3640 divided by 387 is 9 with a remainder of 157.
Record the quotient 9 as the next digit in the result. 
Result so far: 40466.289
Subtract 3483 from 3640 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 12:
387 can be fit into 1570 4 times, resulting in a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 40466.2894
If we take 1548 away from 1570, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
220 divided by 387 is 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 40466.2894
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 14:
387 can be fit into 2200 5 times, resulting in a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 40466.289405
The remainder is 265 after subtracting 1935 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 15:
387 can be fit into 2650 6 times, resulting in a remainder of 328.
Record the quotient 6 as the next digit in the result. 
Result so far: 40466.2894056
Subtracting 2322 from 2650 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 16:
3280 divided by 387 is 8 with a remainder of 184.
Write down 8 as next digit of the result. 
Result so far: 40466.28940568
The remainder is 184 after subtracting 3096 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

In conclusion, the division gives 40466.28940568 with a balance of 1.84e-07.
