544264 ÷ 3 
The aim is to understand the frequency of 3 in 544264.

On to step 1:
3 goes into 5 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
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

Advancing to step 2:
When dividing 24 by 3, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 24 from 24 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Moving on to step 3:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 181.0
The remainder is 1 after subtracting 3 from 4.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Moving on to step 4:
12 divided by 3 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1814.0
Subtracting 12 from 12 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Going ahead to step 5:
3 goes into 6 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 18142.0
Subtract 6 from 6 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Going ahead to step 6:
When dividing 4 by 3, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 181421.0
Deduct 3 from 4 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 181421.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 181421.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 181421.33 with a remainder of 0.001.
