Let's divide 3543 by 3
The aim is to understand the frequency of 3 in 3543.

Advancing to step 1:
If we divide 3 by 3, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Moving on to step 2:
5 divided by 3 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 3 from 5 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Let's proceed to step 3:
The number 3 fits into 24 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtracting 24 from 24 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 3

Let's proceed to step 4:
3 divided by 3 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1181.0
If we take 3 away from 3, 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.

Let's proceed to step 5:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1181.0
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 6:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1181.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 1181.0 with a balance of 0.0.
