We divide 541953 by 3
The aim is to understand the frequency of 3 in 541953.

Moving on to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 3 from 5 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Going ahead to step 2:
3 goes into 24 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 24 from 24 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

On to step 3:
When dividing 1 by 3, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 180.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

Going ahead to step 4:
When dividing 19 by 3, we get 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 1806.0
Subtracting 18 from 19 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

Moving on to step 5:
15 divided by 3 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 18065.0
Subtracting 15 from 15 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 3

Step 6:
3 goes into 3 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 180651.0
Subtract 3 from 3 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 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 180651.0
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.

On to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 180651.0
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.

Our division results in 180651.0 with a remaining 0.0.
