45343 ÷ 30 
The aim is to understand the frequency of 30 in 45343.

Let's proceed to step 1:
If we divide 4 by 30, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 30

Advancing to step 2:
The number 30 fits into 45 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 30 from 45 leaves us with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 30

Let's proceed to step 3:
If we divide 153 by 30, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 3 after subtracting 150 from 153.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 30

Step 4:
If we divide 34 by 30, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 151.0
If we subtract 30 from 34, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 30

Moving on to step 5:
30 can be fit into 43 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1511.0
If we take 30 away from 43, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 6:
When dividing 130 by 30, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 1511.4
Deduct 120 from 130 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1511.43
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1511.433
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 1511.433 and a remainder of 0.001.
