604768 divided by 3 
The aim is to understand the frequency of 3 in 604768.

Let's proceed to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 6 away from 6, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Let's proceed to step 2:
When dividing 0 by 3, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Step 3:
If we divide 4 by 3, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
Deduct 3 from 4 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 3

Going ahead to step 4:
When dividing 17 by 3, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 2015.0
Deduct 15 from 17 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Going ahead to step 5:
3 goes into 26 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 20158.0
Subtracting 24 from 26 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Step 6:
If we divide 28 by 3, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 201589.0
If we subtract 27 from 28, 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.

Going ahead to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 201589.3
If we take 9 away from 10, 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.

On to step 8:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 201589.33
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.

Our division results in 201589.33 with a remaining 0.001.
