736673 ÷ 3 
The aim is to understand the frequency of 3 in 736673.

On to step 1:
3 can be fit into 7 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 6 from 7 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Let's proceed to step 2:
The number 3 fits into 13 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 12 from 13 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 3

On to step 3:
3 can be fit into 16 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 245.0
Deduct 15 from 16 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Advancing to step 4:
If we divide 16 by 3, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2455.0
If we take 15 away from 16, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Moving on to step 5:
3 can be fit into 17 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 24555.0
If we take 15 away from 17, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Advancing to step 6:
3 can be fit into 23 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 245557.0
If we take 21 away from 23, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 245557.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 245557.66
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 245557.66 with a remainder of 0.002.
