We're dividing 621977 by 30 
We want to figure out the number of times 621977 can be divided by 30.

Let's proceed to step 1:
30 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 30

Moving on to step 2:
30 can be fit into 62 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 60 from 62 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 30

Moving on to step 3:
The number 30 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 21 to get 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 30

Going ahead to step 4:
30 goes into 219 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 207.0
Subtracting 210 from 219 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 30

Moving on to step 5:
97 divided by 30 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 2073.0
Deduct 90 from 97 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 30

Advancing to step 6:
If we divide 77 by 30, we get 2 and a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 20732.0
If we take 60 away from 77, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
30 goes into 170 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 20732.5
Deduct 150 from 170 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 20732.56
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 20732.566
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 20732.566 with a remaining 0.002.
