We divide 387441 by 30
The aim is to understand the frequency of 30 in 387441.

Advancing to step 1:
If we divide 3 by 30, we get 0 and 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.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 30

Step 2:
When dividing 38 by 30, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 30 from 38 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 30

Advancing to step 3:
If we divide 87 by 30, we get 2 and a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 60 from 87 to get 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 30

Going ahead to step 4:
If we divide 274 by 30, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 129.0
The remainder is 4 after subtracting 270 from 274.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 30

Advancing to step 5:
When dividing 44 by 30, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1291.0
Subtracting 30 from 44 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 30

On to step 6:
30 goes into 141 4 times with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 12914.0
Subtracting 120 from 141 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
30 goes into 210 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 12914.7
If we take 210 away from 210, 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.

Advancing to step 8:
When dividing 0 by 30, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12914.7
If we subtract 0 from 0, 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 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: 12914.7
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 final outcome is 12914.7, with a leftover of 0.0.
