Let's divide 86915 by 43
Let's see how many times 43 fits into 86915.

Let's proceed to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 43

On to step 2:
86 divided by 43 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 86 from 86 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 43

Step 3:
43 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 43

Step 4:
43 can be fit into 91 2 times, resulting in a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 202.0
If we take 86 away from 91, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 43

Going ahead to step 5:
When dividing 55 by 43, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 2021.0
If we subtract 43 from 55, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 6:
43 can be fit into 120 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 2021.2
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
340 divided by 43 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 2021.27
Subtracting 301 from 340 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
43 goes into 390 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 2021.279
Subtracting 387 from 390 leaves us 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.

Let's proceed to step 9:
43 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2021.279
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.

Moving on to step 10:
300 divided by 43 is 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 2021.27906
Subtract 258 from 300 to 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.

On to step 11:
The number 43 fits into 420 9 times, leaving a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 2021.279069
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
43 can be fit into 330 7 times, resulting in a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 2021.2790697
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 13:
The number 43 fits into 290 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 2021.27906976
Deduct 258 from 290 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 2021.27906976 with a remainder of 3.2e-08.
