We look at the division of 248388 by 87 
We're looking to find how many times 87 goes into 248388.

Step 1:
When dividing 2 by 87, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 87

Step 2:
When dividing 24 by 87, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 87

On to step 3:
87 goes into 248 2 times with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 174 from 248 leaves us with 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 87

Moving on to step 4:
When dividing 743 by 87, we get 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 696 away from 743, we end up with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 87

Moving on to step 5:
When dividing 478 by 87, we get 5 with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 285.0
The remainder is 43 after subtracting 435 from 478.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 87

On to step 6:
438 divided by 87 is 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 2855.0
If we take 435 away from 438, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 87 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2855.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
87 can be fit into 300 3 times, resulting in a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 2855.03
Subtract 261 from 300 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
When dividing 390 by 87, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 2855.034
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
If we divide 420 by 87, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 2855.0344
Subtract 348 from 420 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 2855.0344 with a remainder of 0.00072.
