539273 ÷ 42 
Let's see how many times 42 fits into 539273.

Advancing to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 42

Step 2:
The number 42 fits into 53 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 11 after subtracting 42 from 53.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 42

Let's proceed to step 3:
The number 42 fits into 119 2 times, leaving a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 84 away from 119, we end up with 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 42

Going ahead to step 4:
The number 42 fits into 352 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 128.0
The remainder is 16 after subtracting 336 from 352.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 42

Let's proceed to step 5:
167 divided by 42 is 3 with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 1283.0
If we subtract 126 from 167, we get 41.
Grab the next digit (3) from the dividend, add it to 41, then carry on: 413 / 42

Advancing to step 6:
42 can be fit into 413 9 times, resulting in a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 12839.0
Deduct 378 from 413 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
When dividing 350 by 42, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 12839.8
Subtract 336 from 350 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 42, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 12839.83
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
If we divide 140 by 42, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 12839.833
Deduct 126 from 140 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.

Our division results in 12839.833 with a remaining 0.0014.
