We're dividing 215243 by 87 
We want to figure out the number of times 215243 can be divided by 87.

Advancing to step 1:
2 divided by 87 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 87

Going ahead to step 2:
When dividing 21 by 87, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 87

Moving on to step 3:
87 goes into 215 2 times with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 174 from 215 to get 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 87

Step 4:
If we divide 412 by 87, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 348 away from 412, we end up with 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 87

Moving on to step 5:
87 goes into 644 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 247.0
The remainder is 35 after subtracting 609 from 644.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 87

Advancing to step 6:
If we divide 353 by 87, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 2474.0
Deduct 348 from 353 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 87, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 2474.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
500 divided by 87 is 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 2474.05
Deduct 435 from 500 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
When dividing 650 by 87, we get 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 2474.057
If we take 609 away from 650, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 10:
87 goes into 410 4 times with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 2474.0574
Subtract 348 from 410 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
620 divided by 87 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 2474.05747
If we take 609 away from 620, we end up 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.

On to step 12:
87 goes into 110 1 times with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 2474.057471
Subtracting 87 from 110 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
The number 87 fits into 230 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 2474.0574712
If we take 174 away from 230, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 14:
When dividing 560 by 87, we get 6 with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 2474.05747126
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 2474.05747126 with a remainder of 3.8e-08.
