Let's divide 64841645 by 387
Our goal is to divide 64841645 by 387.

Step 1:
The number 387 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 387

On to step 2:
If we divide 64 by 387, we get 0 and a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 387

Moving on to step 3:
The number 387 fits into 648 1 times, leaving a remainder of 261.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 387 from 648 to get 261.
Bring next digit (4) of the dividend behind the 261 and repeat the process: 2614 / 387

Going ahead to step 4:
2614 divided by 387 is 6 with a remainder of 292.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 292 after subtracting 2322 from 2614.
Include the next digit (1) from the dividend after 292, then repeat: 2921 / 387

Moving on to step 5:
387 goes into 2921 7 times with a remainder of 212.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Deduct 2709 from 2921 and we're left with 212.
Grab the next digit (6) from the dividend, add it to 212, then carry on: 2126 / 387

Moving on to step 6:
If we divide 2126 by 387, we get 5 and a remainder of 191.
The number 5 becomes the next digit in our result. 
Result so far: 1675.0
Subtract 1935 from 2126 to get 191.
Append the next digit (4) from the dividend to 191 and continue with: 1914 / 387

Going ahead to step 7:
The number 387 fits into 1914 4 times, leaving a remainder of 366.
Put 4 as the next digit of the answer. 
Result so far: 16754.0
Subtract 1548 from 1914 to get 366.
Append the next digit (5) from the dividend to 366 and continue with: 3665 / 387

Moving on to step 8:
When dividing 3665 by 387, we get 9 with a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 167549.0
If we take 3483 away from 3665, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 9:
The number 387 fits into 1820 4 times, leaving a remainder of 272.
Write down 4 as next digit of the result. 
Result so far: 167549.4
If we take 1548 away from 1820, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 10:
387 can be fit into 2720 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 167549.47
Deduct 2709 from 2720 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
If we divide 110 by 387, we get 0 and a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 167549.47
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
387 can be fit into 1100 2 times, resulting in a remainder of 326.
Record the quotient 2 as the next digit in the result. 
Result so far: 167549.4702
Deduct 774 from 1100 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 13:
The number 387 fits into 3260 8 times, leaving a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 167549.47028
If we subtract 3096 from 3260, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 14:
When dividing 1640 by 387, we get 4 with a remainder of 92.
The number 4 becomes the next digit in our result. 
Result so far: 167549.470284
Deduct 1548 from 1640 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 15:
387 can be fit into 920 2 times, resulting in a remainder of 146.
Record the quotient 2 as the next digit in the result. 
Result so far: 167549.4702842
The remainder is 146 after subtracting 774 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 16:
387 can be fit into 1460 3 times, resulting in a remainder of 299.
Put 3 as the next digit of the answer. 
Result so far: 167549.47028423
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.

After the division, we end up with 167549.47028423 and a remainder of 2.99e-07.
