We look at the division of 621188 by 75 
We want to divide 621188 by 75.

On to step 1:
75 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 / 75

Going ahead to step 2:
If we divide 62 by 75, we get 0 and a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 75

Moving on to step 3:
If we divide 621 by 75, we get 8 and a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 21 after subtracting 600 from 621.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 75

Let's proceed to step 4:
211 divided by 75 is 2 with a remainder of 61.
The next digit of our result is 2. 
Result so far: 82.0
If we subtract 150 from 211, we get 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 75

Going ahead to step 5:
The number 75 fits into 618 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 828.0
The remainder is 18 after subtracting 600 from 618.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 75

Going ahead to step 6:
188 divided by 75 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 8282.0
The remainder is 38 after subtracting 150 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
75 goes into 380 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 8282.5
If we take 375 away from 380, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
75 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 8282.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 8282.506
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 8282.5066
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 8282.5066 with a remaining 0.0005.
