163863 divided by 87 
We want to figure out the number of times 163863 can be divided by 87.

Advancing to step 1:
87 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 87

Moving on to step 2:
The number 87 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 87

On to step 3:
87 goes into 163 1 times with a remainder of 76.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 87 from 163, we get 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 87

On to step 4:
768 divided by 87 is 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 696 away from 768, we end up with 72.
Grab the next digit (6) from the dividend, add it to 72, then carry on: 726 / 87

Moving on to step 5:
87 goes into 726 8 times with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 188.0
Subtract 696 from 726 to get 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 87

On to step 6:
303 divided by 87 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1883.0
Subtracting 261 from 303 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
87 can be fit into 420 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 1883.4
Deduct 348 from 420 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 8:
The number 87 fits into 720 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 1883.48
If we take 696 away from 720, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
When dividing 240 by 87, we get 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 1883.482
If we subtract 174 from 240, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
If we divide 660 by 87, we get 7 and a remainder of 51.
The next digit of our result is 7. 
Result so far: 1883.4827
The remainder is 51 after subtracting 609 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 11:
87 goes into 510 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 1883.48275
Subtract 435 from 510 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
If we divide 750 by 87, we get 8 and a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 1883.482758
Subtract 696 from 750 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
540 divided by 87 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 1883.4827586
The remainder is 18 after subtracting 522 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
87 can be fit into 180 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1883.48275862
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 1883.48275862, with a leftover of 6e-09.
