512507 ÷ 43 
Our goal is to divide 512507 by 43.

On to step 1:
43 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 43

Moving on to step 2:
When dividing 51 by 43, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 43 from 51, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 43

On to step 3:
43 goes into 82 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 43 from 82 and we're left with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 43

Going ahead to step 4:
43 goes into 395 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtract 387 from 395 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 43

Moving on to step 5:
43 goes into 80 1 times with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1191.0
Subtracting 43 from 80 leaves us with 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 43

Advancing to step 6:
If we divide 377 by 43, we get 8 and a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 11918.0
Subtract 344 from 377 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
43 can be fit into 330 7 times, resulting in a remainder of 29.
The next digit of our result is 7. 
Result so far: 11918.7
Deduct 301 from 330 and we're left with 29.
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 8:
The number 43 fits into 290 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 11918.76
Subtracting 258 from 290 leaves us 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.

On to step 9:
43 can be fit into 320 7 times, resulting in a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 11918.767
If we subtract 301 from 320, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 11918.7674
Subtract 172 from 190 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
If we divide 180 by 43, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 11918.76744
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 11918.76744, with a leftover of 8e-06.
