151965 divided by 30 
The aim is to understand the frequency of 30 in 151965.

Advancing to step 1:
When dividing 1 by 30, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 30

Going ahead 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
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 30

On to step 3:
The number 30 fits into 151 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 150 from 151 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 30

On to step 4:
When dividing 19 by 30, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 30

Moving on to step 5:
30 can be fit into 196 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 506.0
Subtract 180 from 196 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 30

Let's proceed to step 6:
30 can be fit into 165 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5065.0
If we subtract 150 from 165, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 30, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5065.5
Subtracting 150 from 150 leaves us 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.

Step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5065.5
Subtracting 0 from 0 leaves us 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.

Moving on to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5065.5
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.

The quotient of the division is 5065.5, and the remainder is 0.0.
