Let's divide 52568015 by 3
The aim is to understand the frequency of 3 in 52568015.

Let's proceed to step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

Step 2:
When dividing 22 by 3, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 21 from 22 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Advancing to step 3:
3 can be fit into 15 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 175.0
Subtracting 15 from 15 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Advancing to step 4:
3 goes into 6 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 1752.0
If we subtract 6 from 6, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

Advancing to step 5:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 17522.0
Subtract 6 from 8 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 3

Advancing to step 6:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 175226.0
Deduct 18 from 20 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Let's proceed to step 7:
21 divided by 3 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1752267.0
The remainder is 0 after subtracting 21 from 21.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 3

Let's proceed to step 8:
When dividing 5 by 3, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 17522671.0
If we take 3 away from 5, 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.

Advancing to step 9:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 17522671.6
The remainder is 2 after subtracting 18 from 20.
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 10:
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: 17522671.66
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 final result is 17522671.66 with a remainder of 0.002.
