153012 divided by 30 
We want to figure out the number of times 153012 can be divided by 30.

Step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 30

Advancing to step 2:
30 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 30

Advancing to step 3:
When dividing 153 by 30, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 150 away from 153, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 30

Step 4:
30 divided by 30 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 51.0
Subtract 30 from 30 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 30

Step 5:
1 divided by 30 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 510.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 30

Going ahead to step 6:
The number 30 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 5100.0
The remainder is 12 after subtracting 0 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
When dividing 120 by 30, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 5100.4
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 30 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5100.4
If we take 0 away from 0, we end up 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 9:
When dividing 0 by 30, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5100.4
If we take 0 away from 0, we end up 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.

After the division, we end up with 5100.4 and a remainder of 0.0.
