12201487 divided by 387 
We want to divide 12201487 by 387.

Let's proceed to step 1:
When dividing 1 by 387, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 387

On to step 2:
The number 387 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 387

Going ahead to step 3:
122 divided by 387 is 0 with a remainder of 122.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 122 to get 122.
Include the next digit (0) from the dividend after 122, then repeat: 1220 / 387

On to step 4:
When dividing 1220 by 387, we get 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1161 from 1220, we get 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 387

Let's proceed to step 5:
387 can be fit into 591 1 times, resulting in a remainder of 204.
Put 1 as the next digit of the answer. 
Result so far: 31.0
The remainder is 204 after subtracting 387 from 591.
Include the next digit (4) from the dividend after 204, then repeat: 2044 / 387

Going ahead to step 6:
387 can be fit into 2044 5 times, resulting in a remainder of 109.
Put 5 as the next digit of the answer. 
Result so far: 315.0
Deduct 1935 from 2044 and we're left with 109.
Include the next digit (8) from the dividend after 109, then repeat: 1098 / 387

Going ahead to step 7:
1098 divided by 387 is 2 with a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 3152.0
If we subtract 774 from 1098, we get 324.
Include the next digit (7) from the dividend after 324, then repeat: 3247 / 387

Going ahead to step 8:
The number 387 fits into 3247 8 times, leaving a remainder of 151.
Record the quotient 8 as the next digit in the result. 
Result so far: 31528.0
Subtract 3096 from 3247 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 9:
The number 387 fits into 1510 3 times, leaving a remainder of 349.
Put 3 as the next digit of the answer. 
Result so far: 31528.3
Subtracting 1161 from 1510 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 10:
387 can be fit into 3490 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 31528.39
The remainder is 7 after subtracting 3483 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
387 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 31528.39
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
The number 387 fits into 700 1 times, leaving a remainder of 313.
Write down 1 as next digit of the result. 
Result so far: 31528.3901
Deduct 387 from 700 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 13:
The number 387 fits into 3130 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 31528.39018
If we take 3096 away from 3130, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
387 goes into 340 0 times with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 31528.39018
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 15:
When dividing 3400 by 387, we get 8 with a remainder of 304.
Put 8 as the next digit of the answer. 
Result so far: 31528.3901808
The remainder is 304 after subtracting 3096 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 16:
3040 divided by 387 is 7 with a remainder of 331.
The next digit of our result is 7. 
Result so far: 31528.39018087
Subtract 2709 from 3040 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

The quotient of the division is 31528.39018087, and the remainder is 3.31e-07.
