We look at the division of 621295 by 18 
We're looking to find how many times 18 goes into 621295.

Going ahead to step 1:
The number 18 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 18

Moving on to step 2:
The number 18 fits into 62 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 54 from 62 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 18

Advancing to step 3:
If we divide 81 by 18, we get 4 and a remainder of 9.
The next digit of our result is 4. 
Result so far: 34.0
If we subtract 72 from 81, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 18

On to step 4:
The number 18 fits into 92 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 345.0
The remainder is 2 after subtracting 90 from 92.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 18

Going ahead to step 5:
29 divided by 18 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 3451.0
Subtracting 18 from 29 leaves us with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 18

Step 6:
If we divide 115 by 18, we get 6 and a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 34516.0
The remainder is 7 after subtracting 108 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 18 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 34516.3
If we subtract 54 from 70, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
18 can be fit into 160 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 34516.38
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
18 can be fit into 160 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 34516.388
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 34516.388 and a remainder of 0.0016.
