180155 ÷ 3 
The aim is to understand the frequency of 3 in 180155.

Let's proceed to step 1:
3 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Advancing to step 2:
3 goes into 18 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 18 away from 18, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

Let's proceed to step 3:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Let's proceed to step 4:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 600.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Step 5:
The number 3 fits into 15 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6005.0
Subtracting 15 from 15 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 3

Step 6:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 60051.0
The remainder is 2 after subtracting 3 from 5.
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 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 60051.6
Subtracting 18 from 20 leaves us 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.

On to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 60051.66
Subtract 18 from 20 to 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.

The final result is 60051.66 with a remainder of 0.002.
