486311 ÷ 63 
We want to figure out the number of times 486311 can be divided by 63.

Advancing to step 1:
63 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 63

Advancing to step 2:
63 can be fit into 48 0 times, resulting in a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 63

Step 3:
If we divide 486 by 63, we get 7 and a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 441 away from 486, we end up with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 63

On to step 4:
453 divided by 63 is 7 with a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we subtract 441 from 453, we get 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 63

Step 5:
121 divided by 63 is 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 771.0
If we subtract 63 from 121, we get 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 63

Going ahead to step 6:
If we divide 581 by 63, we get 9 and a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 7719.0
Subtract 567 from 581 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 63 fits into 140 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 7719.2
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
The number 63 fits into 140 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 7719.22
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 7719.22, and the remainder is 0.014.
