Let's divide 373377 by 30
The aim is to understand the frequency of 30 in 373377.

Let's proceed to step 1:
3 divided by 30 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 30

Advancing to step 2:
37 divided by 30 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 30 from 37 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 30

Advancing to step 3:
30 goes into 73 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 60 from 73 leaves us with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 30

Let's proceed to step 4:
133 divided by 30 is 4 with a remainder of 13.
The next digit of our result is 4. 
Result so far: 124.0
Deduct 120 from 133 and we're left with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 30

Moving on to step 5:
If we divide 137 by 30, we get 4 and a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 1244.0
Subtracting 120 from 137 leaves us with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 30

Advancing to step 6:
177 divided by 30 is 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 12445.0
If we take 150 away from 177, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
The number 30 fits into 270 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 12445.9
If we subtract 270 from 270, we 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.

Let's proceed to step 8:
30 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12445.9
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.

Moving on to step 9:
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: 12445.9
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.

The final result is 12445.9 with a remainder of 0.0.
