Let's divide 30402708 by 42
Let's see how many times 42 fits into 30402708.

Going ahead to step 1:
42 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 42

Moving on to step 2:
30 divided by 42 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 42

Going ahead to step 3:
42 can be fit into 304 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 294 from 304 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 42

On to step 4:
42 can be fit into 100 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 72.0
If we take 84 away from 100, we end up with 16.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 42

Step 5:
The number 42 fits into 162 3 times, leaving a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 723.0
Deduct 126 from 162 and we're left with 36.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 42

Step 6:
42 goes into 367 8 times with a remainder of 31.
The next digit of our result is 8. 
Result so far: 7238.0
If we take 336 away from 367, we end up with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 42

Moving on to step 7:
42 can be fit into 310 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 72387.0
If we subtract 294 from 310, we get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 42

Advancing to step 8:
42 can be fit into 168 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 723874.0
Subtracting 168 from 168 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 42, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 723874.0
If we subtract 0 from 0, we 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.

Going ahead to step 10:
42 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 723874.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 723874.0, and the remainder is 0.0.
