We look at the division of 349362 by 3 
The aim is to understand the frequency of 3 in 349362.

Going ahead to step 1:
3 divided by 3 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

On to step 2:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 3 from 4, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

On to step 3:
If we divide 19 by 3, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we subtract 18 from 19, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Going ahead to step 4:
If we divide 13 by 3, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1164.0
Deduct 12 from 13 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 3

Step 5:
If we divide 16 by 3, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 11645.0
Subtracting 15 from 16 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 3

On to step 6:
3 goes into 12 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 116454.0
The remainder is 0 after subtracting 12 from 12.
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:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 116454.0
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.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 116454.0
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.

The final result is 116454.0 with a remainder of 0.0.
