515285 ÷ 43 
We're looking to find how many times 43 goes into 515285.

Step 1:
43 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 43

Going ahead to step 2:
43 goes into 51 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 8 after subtracting 43 from 51.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 43

Going ahead to step 3:
43 goes into 85 1 times with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 42 after subtracting 43 from 85.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 43

Advancing to step 4:
422 divided by 43 is 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 119.0
If we take 387 away from 422, we end up with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 43

Step 5:
358 divided by 43 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 1198.0
Subtracting 344 from 358 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 43

Let's proceed to step 6:
When dividing 145 by 43, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 11983.0
Subtracting 129 from 145 leaves us with 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 7:
When dividing 160 by 43, we get 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 11983.3
Subtract 129 from 160 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
When dividing 310 by 43, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 11983.37
If we take 301 away from 310, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
If we divide 90 by 43, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 11983.372
If we subtract 86 from 90, we 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.

Let's proceed to step 10:
40 divided by 43 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 11983.372
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.

Let's proceed to step 11:
400 divided by 43 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 11983.37209
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
The number 43 fits into 130 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 11983.372093
Subtracting 129 from 130 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
The number 43 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 11983.372093
Subtracting 0 from 10 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.

Step 14:
If we divide 100 by 43, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 11983.37209302
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 11983.37209302, and the remainder is 1.4e-08.
