540909 ÷ 43 
We want to divide 540909 by 43.

Advancing to step 1:
43 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 43

Going ahead to step 2:
54 divided by 43 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 43 away from 54, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 43

Let's proceed to step 3:
43 goes into 110 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 86 from 110 leaves us with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 43

Advancing to step 4:
43 goes into 249 5 times with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 125.0
If we take 215 away from 249, we end up with 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 43

Moving on to step 5:
43 can be fit into 340 7 times, resulting in a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 1257.0
Subtract 301 from 340 to get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 43

Step 6:
If we divide 399 by 43, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 12579.0
If we subtract 387 from 399, 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.

On to step 7:
The number 43 fits into 120 2 times, leaving a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 12579.2
Subtracting 86 from 120 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
340 divided by 43 is 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 12579.27
If we take 301 away from 340, we end up 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.

Let's proceed to step 9:
When dividing 390 by 43, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 12579.279
The remainder is 3 after subtracting 387 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
When dividing 30 by 43, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 12579.279
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
43 can be fit into 300 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 12579.27906
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
43 goes into 420 9 times with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 12579.279069
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.

On to step 13:
If we divide 330 by 43, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 12579.2790697
If we take 301 away from 330, we end up 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.

Let's proceed to step 14:
43 goes into 290 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 12579.27906976
If we take 258 away from 290, we end up 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 quotient of the division is 12579.27906976, and the remainder is 3.2e-08.
