Let's divide 24139 by 86
Our goal is to divide 24139 by 86.

Going ahead to step 1:
If we divide 2 by 86, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 86

Let's proceed to step 2:
24 divided by 86 is 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 86

Advancing to step 3:
When dividing 241 by 86, we get 2 with a remainder of 69.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 172 from 241 and we're left with 69.
Include the next digit (3) from the dividend after 69, then repeat: 693 / 86

Going ahead to step 4:
The number 86 fits into 693 8 times, leaving a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 688 from 693 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 86

Let's proceed to step 5:
When dividing 59 by 86, we get 0 with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 280.0
The remainder is 59 after subtracting 0 from 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 6:
When dividing 590 by 86, we get 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 280.6
Subtract 516 from 590 to 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.

Let's proceed to step 7:
86 can be fit into 740 8 times, resulting in a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 280.68
Subtract 688 from 740 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
86 can be fit into 520 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 280.686
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 86, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 280.686
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
86 goes into 400 4 times with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 280.68604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
560 divided by 86 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 280.686046
Subtracting 516 from 560 leaves us 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 12:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 280.6860465
If we take 430 away from 440, we end up 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.

Going ahead to step 13:
If we divide 100 by 86, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 280.68604651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 280.68604651 with a remaining 1.4e-08.
