We divide 486086 by 9
We're looking to find how many times 9 goes into 486086.

Advancing to step 1:
4 divided by 9 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 9

Moving on to step 2:
The number 9 fits into 48 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 45 away from 48, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 9

Step 3:
If we divide 36 by 9, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we take 36 away from 36, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 9

On to step 4:
When dividing 0 by 9, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 540.0
Subtract 0 from 0 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 9

Step 5:
When dividing 8 by 9, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 5400.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 9

Let's proceed to step 6:
If we divide 86 by 9, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 54009.0
Deduct 81 from 86 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 54009.5
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
9 can be fit into 50 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 54009.55
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 54009.55, with a leftover of 0.005.
