We look at the division of 300606 by 75 
Let's see how many times 75 fits into 300606.

Going ahead to step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 75

Advancing to step 2:
75 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 75

On to step 3:
The number 75 fits into 300 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 300 from 300 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 75

Going ahead to step 4:
If we divide 6 by 75, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 75

Step 5:
75 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
Subtract 0 from 60 to get 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 75

Advancing to step 6:
If we divide 606 by 75, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 4008.0
The remainder is 6 after subtracting 600 from 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 75 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 4008.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
75 can be fit into 600 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 4008.08
If we subtract 600 from 600, we 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 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4008.08
If we subtract 0 from 0, we 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 10:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4008.08
Deduct 0 from 0 and we're left 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.

Our division results in 4008.08 with a remaining 0.0.
