We divide 621880 by 42
Let's see how many times 42 fits into 621880.

Going ahead to step 1:
The number 42 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 42

Going ahead to step 2:
If we divide 62 by 42, we get 1 and a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 20 after subtracting 42 from 62.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 42

On to step 3:
If we divide 201 by 42, we get 4 and a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 168 from 201 to get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 42

On to step 4:
If we divide 338 by 42, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 148.0
The remainder is 2 after subtracting 336 from 338.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 42

Going ahead to step 5:
28 divided by 42 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 1480.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 42

Let's proceed to step 6:
When dividing 280 by 42, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 14806.0
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
If we divide 280 by 42, we get 6 and a remainder of 28.
The next digit of our result is 6. 
Result so far: 14806.6
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
42 goes into 280 6 times with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 14806.66
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 14806.66 and a remainder of 0.028.
