243287 divided by 86 
Our goal is to divide 243287 by 86.

Step 1:
86 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 86

Advancing to step 2:
86 goes into 24 0 times with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 86

Going ahead to step 3:
When dividing 243 by 86, we get 2 with a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 172 from 243, we get 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 86

Let's proceed to step 4:
If we divide 712 by 86, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 688 from 712 leaves us with 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 86

Moving on to step 5:
The number 86 fits into 248 2 times, leaving a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 282.0
The remainder is 76 after subtracting 172 from 248.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 86

Advancing to step 6:
767 divided by 86 is 8 with a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 2828.0
The remainder is 79 after subtracting 688 from 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 7:
86 goes into 790 9 times with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 2828.9
If we subtract 774 from 790, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
When dividing 160 by 86, we get 1 with a remainder of 74.
The next digit of our result is 1. 
Result so far: 2828.91
If we subtract 86 from 160, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 9:
86 can be fit into 740 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 2828.918
If we take 688 away from 740, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
If we divide 520 by 86, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 2828.9186
Subtract 516 from 520 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
86 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2828.9186
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
If we divide 400 by 86, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 2828.918604
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
When dividing 560 by 86, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 2828.9186046
Deduct 516 from 560 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
86 goes into 440 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2828.91860465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 2828.91860465 with a remaining 1e-08.
