We divide 243399 by 87
We're looking to find how many times 87 goes into 243399.

Advancing to step 1:
87 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 87

Step 2:
87 goes into 24 0 times with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 87

Let's proceed to step 3:
243 divided by 87 is 2 with a remainder of 69.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 174 from 243 and we're left with 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 87

Step 4:
When dividing 693 by 87, we get 7 with a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 609 from 693 and we're left with 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 87

On to step 5:
If we divide 849 by 87, we get 9 and a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 279.0
Deduct 783 from 849 and we're left with 66.
Append the next digit (9) from the dividend to 66 and continue with: 669 / 87

Step 6:
87 can be fit into 669 7 times, resulting in a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 2797.0
Deduct 609 from 669 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
600 divided by 87 is 6 with a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 2797.6
The remainder is 78 after subtracting 522 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 8:
If we divide 780 by 87, we get 8 and a remainder of 84.
The number 8 becomes the next digit in our result. 
Result so far: 2797.68
If we take 696 away from 780, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 2797.689
If we take 783 away from 840, we end up 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.

Step 10:
570 divided by 87 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 2797.6896
Subtract 522 from 570 to 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 11:
The number 87 fits into 480 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 2797.68965
Subtracting 435 from 480 leaves us 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.

Moving on to step 12:
The number 87 fits into 450 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2797.689655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 2797.689655, and the remainder is 1.5e-06.
