We divide 30150 by 10
Let's see how many times 10 fits into 30150.

On to step 1:
If we divide 3 by 10, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 10

Step 2:
The number 10 fits into 30 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 30 away from 30, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 10

Advancing to step 3:
10 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 10

Going ahead to step 4:
10 can be fit into 15 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 301.0
Deduct 10 from 15 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 10

Advancing to step 5:
10 can be fit into 50 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3015.0
Deduct 50 from 50 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 6:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3015.0
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.

Going ahead to step 7:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3015.0
Subtract 0 from 0 to 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 3015.0, and the remainder is 0.0.
