We divide 81024109 by 387
We're looking to find how many times 387 goes into 81024109.

Moving on to step 1:
When dividing 8 by 387, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 387

Going ahead to step 2:
When dividing 81 by 387, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 387

Let's proceed to step 3:
810 divided by 387 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 774 from 810, we get 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 387

Step 4:
If we divide 362 by 387, we get 0 and a remainder of 362.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtracting 0 from 362 leaves us with 362.
Take the next digit (4) from the dividend and append it to 362, then repeat: 3624 / 387

Advancing to step 5:
The number 387 fits into 3624 9 times, leaving a remainder of 141.
Put 9 as the next digit of the answer. 
Result so far: 209.0
Subtracting 3483 from 3624 leaves us with 141.
Append the next digit (1) from the dividend to 141 and continue with: 1411 / 387

Going ahead to step 6:
The number 387 fits into 1411 3 times, leaving a remainder of 250.
The number 3 becomes the next digit in our result. 
Result so far: 2093.0
If we subtract 1161 from 1411, we get 250.
Bring next digit (0) of the dividend behind the 250 and repeat the process: 2500 / 387

Advancing to step 7:
2500 divided by 387 is 6 with a remainder of 178.
The next digit of our result is 6. 
Result so far: 20936.0
If we take 2322 away from 2500, we end up with 178.
Append the next digit (9) from the dividend to 178 and continue with: 1789 / 387

Let's proceed to step 8:
1789 divided by 387 is 4 with a remainder of 241.
Use 4 as the next digit of our solution. 
Result so far: 209364.0
Subtract 1548 from 1789 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 9:
2410 divided by 387 is 6 with a remainder of 88.
The next digit of our result is 6. 
Result so far: 209364.6
The remainder is 88 after subtracting 2322 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
The number 387 fits into 880 2 times, leaving a remainder of 106.
Write down 2 as next digit of the result. 
Result so far: 209364.62
The remainder is 106 after subtracting 774 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
387 can be fit into 1060 2 times, resulting in a remainder of 286.
Use 2 as the next digit of our solution. 
Result so far: 209364.622
Subtract 774 from 1060 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

The final result is 209364.622 with a remainder of 0.0286.
