525293 divided by 3 
The aim is to understand the frequency of 3 in 525293.

Step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 3 from 5 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 3

Moving on to step 2:
When dividing 22 by 3, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtract 21 from 22 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Advancing to step 3:
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: 175.0
If we subtract 15 from 15, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Going ahead to step 4:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1750.0
If we take 0 away from 2, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Advancing to step 5:
If we divide 29 by 3, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 17509.0
Subtract 27 from 29 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Step 6:
If we divide 23 by 3, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 175097.0
Subtracting 21 from 23 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.

Moving on 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: 175097.6
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.

Let's proceed to step 8:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 175097.66
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 quotient of the division is 175097.66, and the remainder is 0.002.
