We divide 178741 by 3
The aim is to understand the frequency of 3 in 178741.

Advancing to step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Let's proceed to step 2:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 2 after subtracting 15 from 17.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 3

On to step 3:
28 divided by 3 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 59.0
If we subtract 27 from 28, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Advancing to step 4:
17 divided by 3 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 595.0
Subtracting 15 from 17 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Going ahead to step 5:
24 divided by 3 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 5958.0
If we subtract 24 from 24, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Let's proceed to step 6:
If we divide 1 by 3, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 59580.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 59580.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 59580.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 59580.33, with a leftover of 0.001.
