We're dividing 577900 by 3 
The aim is to understand the frequency of 3 in 577900.

Let's proceed to step 1:
3 can be fit into 5 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

Moving on to step 2:
3 goes into 27 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 27 from 27 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Going ahead to step 3:
The number 3 fits into 7 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
The remainder is 1 after subtracting 6 from 7.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Moving on to step 4:
3 goes into 19 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1926.0
If we subtract 18 from 19, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Let's proceed to step 5:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 19263.0
The remainder is 1 after subtracting 9 from 10.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 3

Going ahead to step 6:
If we divide 10 by 3, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 192633.0
If we subtract 9 from 10, we 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.

Step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 192633.3
Deduct 9 from 10 and we're left 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 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 192633.33
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 quotient of the division is 192633.33, and the remainder is 0.001.
