We divide 485165 by 1
We want to figure out the number of times 485165 can be divided by 1.

On to step 1:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Moving on to step 2:
If we divide 8 by 1, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we subtract 8 from 8, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Let's proceed to step 3:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 485.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Let's proceed to step 4:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 4851.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Step 5:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 48516.0
If we subtract 6 from 6, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

On to step 6:
1 goes into 5 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 485165.0
If we take 5 away from 5, we end up 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.

Going ahead to step 7:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 485165.0
The remainder is 0 after subtracting 0 from 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 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 485165.0
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.

The quotient of the division is 485165.0, and the remainder is 0.0.
