We look at the division of 156728 by 3 
The aim is to understand the frequency of 3 in 156728.

Advancing to step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Moving on to step 2:
When dividing 15 by 3, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 15 from 15 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 3

Step 3:
The number 3 fits into 6 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Subtract 6 from 6 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Going ahead to step 4:
3 goes into 7 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 522.0
If we subtract 6 from 7, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 3

Moving on to step 5:
12 divided by 3 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 5224.0
Subtract 12 from 12 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 6:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 52242.0
Subtract 6 from 8 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.

Advancing to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 52242.6
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.

Let's proceed to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 52242.66
If we take 18 away from 20, we end up 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.

The quotient of the division is 52242.66, and the remainder is 0.002.
