We're dividing 571576 by 3 
The aim is to understand the frequency of 3 in 571576.

Advancing to step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 3 from 5 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 3

Let's proceed to step 2:
3 goes into 27 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 27 away from 27, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Step 3:
When dividing 1 by 3, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Advancing to step 4:
The number 3 fits into 15 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1905.0
Subtract 15 from 15 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Moving on to step 5:
3 can be fit into 7 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 19052.0
Deduct 6 from 7 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Let's proceed to step 6:
16 divided by 3 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 190525.0
If we take 15 away from 16, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 190525.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 190525.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 190525.33, with a leftover of 0.001.
