Let's divide 346656 by 3
The aim is to understand the frequency of 3 in 346656.

On to step 1:
When dividing 3 by 3, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 3 from 3 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 2:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 3 from 4 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Going ahead to step 3:
3 can be fit into 16 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 115.0
The remainder is 1 after subtracting 15 from 16.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 3

Step 4:
When dividing 16 by 3, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 1155.0
Subtracting 15 from 16 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Let's proceed to step 5:
When dividing 15 by 3, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11555.0
If we subtract 15 from 15, we get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Advancing to step 6:
3 goes into 6 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 115552.0
Subtracting 6 from 6 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.

Step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 115552.0
Deduct 0 from 0 and we're left 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 8:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 115552.0
Subtracting 0 from 0 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.

Our division results in 115552.0 with a remaining 0.0.
