Let's see how many times 42 fits into 346668.

On to step 1:
3 divided by 42 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 42

Let's proceed to step 2:
If we divide 34 by 42, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 42

Moving on to step 3:
When dividing 346 by 42, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 336 from 346 to get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 42

Moving on to step 4:
106 divided by 42 is 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 82.0
If we take 84 away from 106, we end up with 22.
Take the next digit (6) from the dividend and append it to 22, then repeat: 226 / 42

Advancing to step 5:
226 divided by 42 is 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 825.0
If we subtract 210 from 226, we get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 42

Going ahead to step 6:
168 divided by 42 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 8254.0
Subtract 168 from 168 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.

Moving on to step 7:
42 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8254.0
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.

Advancing to step 8:
42 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8254.0
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.

In conclusion, the division gives 8254.0 with a balance of 0.0.
