We're dividing 845435 by 30 
The aim is to understand the frequency of 30 in 845435.

On to step 1:
30 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 30

Advancing to step 2:
30 goes into 84 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 24 after subtracting 60 from 84.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 30

Let's proceed to step 3:
30 can be fit into 245 8 times, resulting in a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 5 after subtracting 240 from 245.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 30

Going ahead to step 4:
30 goes into 54 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Subtracting 30 from 54 leaves us with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 30

Step 5:
When dividing 243 by 30, we get 8 with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 2818.0
If we subtract 240 from 243, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 30

Going ahead to step 6:
When dividing 35 by 30, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 28181.0
The remainder is 5 after subtracting 30 from 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
30 goes into 50 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 28181.1
If we subtract 30 from 50, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 30, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 28181.16
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 28181.166
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 28181.166, with a leftover of 0.002.
