We divide 186154 by 3
The aim is to understand the frequency of 3 in 186154.

Moving on to step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

On to step 2:
If we divide 18 by 3, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 18 away from 18, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

On to step 3:
3 goes into 6 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we subtract 6 from 6, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

Advancing to step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 620.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

On to step 5:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6205.0
Subtracting 15 from 15 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Step 6:
4 divided by 3 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 62051.0
Deduct 3 from 4 and we're left 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.

Let's proceed to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 62051.3
If we take 9 away from 10, 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.

Moving on to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 62051.33
Subtract 9 from 10 to 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.

Our division results in 62051.33 with a remaining 0.001.
