Let's divide 512980 by 43
We want to divide 512980 by 43.

Step 1:
5 divided by 43 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 43

Going ahead to step 2:
43 goes into 51 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 43 from 51 and we're left with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 43

Step 3:
82 divided by 43 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 43 from 82, we get 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 43

On to step 4:
The number 43 fits into 399 9 times, leaving a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 119.0
The remainder is 12 after subtracting 387 from 399.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 43

Step 5:
The number 43 fits into 128 2 times, leaving a remainder of 42.
The next digit of our result is 2. 
Result so far: 1192.0
Deduct 86 from 128 and we're left with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 43

Let's proceed to step 6:
When dividing 420 by 43, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 11929.0
Deduct 387 from 420 and we're left 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.

Going ahead to step 7:
43 can be fit into 330 7 times, resulting in a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 11929.7
Subtracting 301 from 330 leaves us 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:
If we divide 290 by 43, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 11929.76
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
If we divide 320 by 43, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 11929.767
The remainder is 19 after subtracting 301 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
43 goes into 190 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 11929.7674
If we subtract 172 from 190, we 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.

Moving on to step 11:
When dividing 180 by 43, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 11929.76744
If we subtract 172 from 180, we get 8.
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 11929.76744, with a leftover of 8e-06.
