We're dividing 78528 by 3 
The aim is to understand the frequency of 3 in 78528.

Step 1:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Let's proceed to step 2:
3 can be fit into 18 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Let's proceed to step 3:
3 goes into 5 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 261.0
The remainder is 2 after subtracting 3 from 5.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Going ahead to step 4:
The number 3 fits into 22 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 2617.0
Deduct 21 from 22 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Advancing to step 5:
3 goes into 18 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 26176.0
Deduct 18 from 18 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.

Going ahead to step 6:
When dividing 0 by 3, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26176.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26176.0
If we subtract 0 from 0, we get 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 final result is 26176.0 with a remainder of 0.0.
