30570030 ÷ 75 
We want to figure out the number of times 30570030 can be divided by 75.

Moving on to step 1:
When dividing 3 by 75, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 75

Let's proceed to step 2:
If we divide 30 by 75, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 75

Going ahead to step 3:
The number 75 fits into 305 4 times, leaving a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 300 from 305 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 75

Let's proceed to step 4:
75 can be fit into 57 0 times, resulting in a remainder of 57.
The next digit of our result is 0. 
Result so far: 40.0
If we subtract 0 from 57, we get 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 75

Going ahead to step 5:
75 goes into 570 7 times with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 407.0
If we take 525 away from 570, we end up with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 75

Advancing to step 6:
450 divided by 75 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 4076.0
Subtracting 450 from 450 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 75

Advancing to step 7:
If we divide 3 by 75, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 40760.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 75

Let's proceed to step 8:
75 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 407600.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
If we divide 300 by 75, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 407600.4
The remainder is 0 after subtracting 300 from 300.
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 407600.4
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.

On to step 11:
75 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 407600.4
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.

The quotient of the division is 407600.4, and the remainder is 0.0.
