We divide 486151 by 3
Our goal is to divide 486151 by 3.

Advancing to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 3

Step 2:
3 can be fit into 18 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 18 away from 18, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Let's proceed to step 3:
The number 3 fits into 6 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 162.0
The remainder is 0 after subtracting 6 from 6.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

On to step 4:
3 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 1620.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Moving on to step 5:
3 goes into 15 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 16205.0
Deduct 15 from 15 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

On to step 6:
1 divided by 3 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 162050.0
The remainder is 1 after subtracting 0 from 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 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 162050.3
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.

On to step 8:
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: 162050.33
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.

In conclusion, the division gives 162050.33 with a balance of 0.001.
