376212 divided by 30 
The aim is to understand the frequency of 30 in 376212.

Step 1:
30 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 30

Advancing to step 2:
30 goes into 37 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 30 from 37 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 30

Going ahead to step 3:
30 can be fit into 76 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 60 from 76, we get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 30

Step 4:
30 goes into 162 5 times with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 125.0
Subtract 150 from 162 to get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 30

On to step 5:
30 can be fit into 121 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1254.0
Deduct 120 from 121 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 30

On to step 6:
12 divided by 30 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 12540.0
If we take 0 away from 12, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
30 can be fit into 120 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 12540.4
Subtracting 120 from 120 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.

On to step 8:
30 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12540.4
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.

Going ahead to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12540.4
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.

The quotient of the division is 12540.4, and the remainder is 0.0.
