We divide 485201 by 3
We want to figure out the number of times 485201 can be divided by 3.

Let's proceed to step 1:
4 divided by 3 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 3 away from 4, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

Advancing to step 2:
3 goes into 18 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 18 away from 18, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Going ahead to step 3:
5 divided by 3 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
The remainder is 2 after subtracting 3 from 5.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

On to step 4:
3 can be fit into 22 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 1617.0
Deduct 21 from 22 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Going ahead to step 5:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 16173.0
The remainder is 1 after subtracting 9 from 10.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

Step 6:
When dividing 11 by 3, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 161733.0
Subtract 9 from 11 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 161733.6
Subtracting 18 from 20 leaves us 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.

Advancing to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 161733.66
Subtracting 18 from 20 leaves us 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.

The final result is 161733.66 with a remainder of 0.002.
