Let's divide 664751 by 3
The aim is to understand the frequency of 3 in 664751.

Let's proceed to step 1:
3 goes into 6 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 6 from 6, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

Advancing to step 2:
If we divide 6 by 3, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Moving on to step 3:
4 divided by 3 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Deduct 3 from 4 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Advancing to step 4:
17 divided by 3 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 2215.0
The remainder is 2 after subtracting 15 from 17.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 3

Step 5:
The number 3 fits into 25 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 22158.0
The remainder is 1 after subtracting 24 from 25.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Advancing to step 6:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 221583.0
If we take 9 away from 11, 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.

Moving on to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 221583.6
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 221583.66
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 221583.66 and a remainder of 0.002.
