We look at the division of 56785803 by 3 
The aim is to understand the frequency of 3 in 56785803.

Let's proceed to step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 3 away from 5, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 3

Step 2:
If we divide 26 by 3, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 24 from 26, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 3

Moving on to step 3:
3 goes into 27 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 189.0
Subtracting 27 from 27 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

Moving on to step 4:
8 divided by 3 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 1892.0
Subtracting 6 from 8 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Moving on to step 5:
The number 3 fits into 25 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 18928.0
Subtracting 24 from 25 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

Going ahead to step 6:
The number 3 fits into 18 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 189286.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Advancing to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1892860.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 3

Let's proceed to step 8:
When dividing 3 by 3, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 18928601.0
Subtracting 3 from 3 leaves us 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.

On to step 9:
0 divided by 3 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18928601.0
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.

Advancing to step 10:
3 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18928601.0
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.

The final result is 18928601.0 with a remainder of 0.0.
