158481 ÷ 3 
The aim is to understand the frequency of 3 in 158481.

On to step 1:
When dividing 1 by 3, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Moving on to step 2:
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: 5.0
The remainder is 0 after subtracting 15 from 15.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 3:
8 divided by 3 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 52.0
Subtract 6 from 8 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 3

Going ahead to step 4:
3 can be fit into 24 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 528.0
Subtract 24 from 24 to get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Moving on to step 5:
The number 3 fits into 8 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 5282.0
Deduct 6 from 8 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Going ahead to step 6:
21 divided by 3 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 52827.0
Deduct 21 from 21 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 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 52827.0
If we take 0 away from 0, we end up 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.

Let's proceed to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 52827.0
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.

The quotient of the division is 52827.0, and the remainder is 0.0.
