We divide 540015 by 42
We want to figure out the number of times 540015 can be divided by 42.

Let's proceed to step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 42

Advancing to step 2:
42 goes into 54 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 12 after subtracting 42 from 54.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 42

Advancing to step 3:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 84 from 120 leaves us with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 42

Let's proceed to step 4:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we take 336 away from 360, we end up with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 42

Going ahead to step 5:
42 can be fit into 241 5 times, resulting in a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 1285.0
If we take 210 away from 241, we end up with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 42

Let's proceed to step 6:
42 goes into 315 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 12857.0
Subtract 294 from 315 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
The number 42 fits into 210 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12857.5
The remainder is 0 after subtracting 210 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
42 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12857.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 42, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12857.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 12857.5 with a remaining 0.0.
