151009 divided by 30 
We want to divide 151009 by 30.

Going ahead to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 30

On to step 2:
30 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 30

Step 3:
30 goes into 151 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 1 after subtracting 150 from 151.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 30

Going ahead to step 4:
10 divided by 30 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 30

Going ahead to step 5:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 503.0
The remainder is 10 after subtracting 90 from 100.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 30

Let's proceed to step 6:
The number 30 fits into 109 3 times, leaving a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 5033.0
The remainder is 19 after subtracting 90 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 30 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 5033.6
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 goes into 100 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 5033.63
Deduct 90 from 100 and we're left 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.

On to step 9:
30 goes into 100 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 5033.633
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 5033.633 with a remaining 0.001.
