Let's divide 215643 by 87
We want to figure out the number of times 215643 can be divided by 87.

Step 1:
The number 87 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 87

On to step 2:
21 divided by 87 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 87

On to step 3:
215 divided by 87 is 2 with a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 174 from 215 and we're left with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 87

Advancing to step 4:
87 goes into 416 4 times with a remainder of 68.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 348 from 416 leaves us with 68.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 87

Let's proceed to step 5:
87 can be fit into 684 7 times, resulting in a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 247.0
If we take 609 away from 684, we end up with 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 87

Advancing to step 6:
If we divide 753 by 87, we get 8 and a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 2478.0
Deduct 696 from 753 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
87 goes into 570 6 times with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 2478.6
If we subtract 522 from 570, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
When dividing 480 by 87, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 2478.65
The remainder is 45 after subtracting 435 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
450 divided by 87 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2478.655
The remainder is 15 after subtracting 435 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 2478.655 with a remaining 0.0015.
