We look at the division of 43539 by 74 
We're looking to find how many times 74 goes into 43539.

On to step 1:
4 divided by 74 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 74

Moving on to step 2:
74 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 74

Moving on to step 3:
435 divided by 74 is 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 65 after subtracting 370 from 435.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 74

Let's proceed to step 4:
653 divided by 74 is 8 with a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 58.0
If we take 592 away from 653, we end up with 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 74

On to step 5:
74 can be fit into 619 8 times, resulting in a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 588.0
The remainder is 27 after subtracting 592 from 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 6:
74 goes into 270 3 times with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 588.3
Subtracting 222 from 270 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
The number 74 fits into 480 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 588.36
If we take 444 away from 480, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
74 goes into 360 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 588.364
Subtract 296 from 360 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
The number 74 fits into 640 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 588.3648
If we subtract 592 from 640, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
74 can be fit into 480 6 times, resulting in a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 588.36486
Subtracting 444 from 480 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
74 goes into 360 4 times with a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 588.364864
If we take 296 away from 360, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
640 divided by 74 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 588.3648648
The remainder is 48 after subtracting 592 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
74 goes into 480 6 times with a remainder of 36.
The next digit of our result is 6. 
Result so far: 588.36486486
Deduct 444 from 480 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 588.36486486 with a remainder of 3.6e-08.
