Let's divide 335772 by 3
The aim is to understand the frequency of 3 in 335772.

Let's proceed to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 3

Moving on to step 2:
3 divided by 3 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Let's proceed to step 3:
3 goes into 5 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 111.0
If we subtract 3 from 5, we get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 3

On to step 4:
27 divided by 3 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 1119.0
If we subtract 27 from 27, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

Advancing to step 5:
If we divide 7 by 3, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 11192.0
Deduct 6 from 7 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Going ahead to step 6:
3 can be fit into 12 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 111924.0
Subtracting 12 from 12 leaves us 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.

Advancing to step 7:
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: 111924.0
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.

Advancing 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: 111924.0
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.

The final result is 111924.0 with a remainder of 0.0.
