We divide 86886189 by 387
We want to figure out the number of times 86886189 can be divided by 387.

On to step 1:
387 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 387

Going ahead to step 2:
When dividing 86 by 387, we get 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (8) of the dividend behind the 86 and repeat the process: 868 / 387

Advancing to step 3:
387 can be fit into 868 2 times, resulting in a remainder of 94.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 774 from 868, we get 94.
Grab the next digit (8) from the dividend, add it to 94, then carry on: 948 / 387

Step 4:
387 goes into 948 2 times with a remainder of 174.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 774 from 948, we get 174.
Include the next digit (6) from the dividend after 174, then repeat: 1746 / 387

Moving on to step 5:
When dividing 1746 by 387, we get 4 with a remainder of 198.
The next digit of our result is 4. 
Result so far: 224.0
Subtracting 1548 from 1746 leaves us with 198.
Fetch the next digit (1) from the dividend, attach it to 198 and continue: 1981 / 387

On to step 6:
1981 divided by 387 is 5 with a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 2245.0
Deduct 1935 from 1981 and we're left with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 387

Going ahead to step 7:
When dividing 468 by 387, we get 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 22451.0
Subtracting 387 from 468 leaves us with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 387

Going ahead to step 8:
When dividing 819 by 387, we get 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 224512.0
If we take 774 away from 819, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
387 can be fit into 450 1 times, resulting in a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 224512.1
Deduct 387 from 450 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 10:
If we divide 630 by 387, we get 1 and a remainder of 243.
The number 1 becomes the next digit in our result. 
Result so far: 224512.11
The remainder is 243 after subtracting 387 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

The final outcome is 224512.11, with a leftover of 0.243.
