476603 divided by 3 
The aim is to understand the frequency of 3 in 476603.

On to step 1:
4 divided by 3 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Going ahead to step 2:
3 can be fit into 17 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 15 from 17 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Going ahead to step 3:
When dividing 26 by 3, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 158.0
Subtract 24 from 26 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Going ahead to step 4:
3 goes into 26 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1588.0
Subtract 24 from 26 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

On to step 5:
3 goes into 20 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 15886.0
If we take 18 away from 20, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Step 6:
3 goes into 23 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 158867.0
If we take 21 away from 23, 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.

Moving on to step 7:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 158867.6
If we take 18 away from 20, 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.

On to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 158867.66
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.

The quotient of the division is 158867.66, and the remainder is 0.002.
