We look at the division of 300475 by 30 
We want to divide 300475 by 30.

On to step 1:
When dividing 3 by 30, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 30

Going ahead to step 2:
The number 30 fits into 30 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 30 from 30.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 30

Advancing to step 3:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 30

Advancing to step 4:
When dividing 4 by 30, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtract 0 from 4 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 30

Going ahead to step 5:
When dividing 47 by 30, we get 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1001.0
The remainder is 17 after subtracting 30 from 47.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 30

Let's proceed to step 6:
30 goes into 175 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10015.0
The remainder is 25 after subtracting 150 from 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
If we divide 250 by 30, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 10015.8
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 10015.83
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 10015.833
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 10015.833, with a leftover of 0.001.
