486231 ÷ 3 
Let's see how many times 3 fits into 486231.

Step 1:
3 goes into 4 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 3 from 4.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

On to step 2:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 18 away from 18, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Moving on to step 3:
3 goes into 6 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 162.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Let's proceed to step 4:
When dividing 2 by 3, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 1620.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Advancing to step 5:
If we divide 23 by 3, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 16207.0
Subtract 21 from 23 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Advancing to step 6:
3 goes into 21 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 162077.0
Subtracting 21 from 21 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 7:
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: 162077.0
Subtracting 0 from 0 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.

Step 8:
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: 162077.0
Subtracting 0 from 0 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.

Our division results in 162077.0 with a remaining 0.0.
