486865 ÷ 75 
We want to figure out the number of times 486865 can be divided by 75.

Step 1:
75 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 75

On to step 2:
The number 75 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 75

Going ahead to step 3:
75 goes into 486 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 450 from 486 to get 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 75

On to step 4:
The number 75 fits into 368 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 300 from 368, we get 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 75

Advancing to step 5:
The number 75 fits into 686 9 times, leaving a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 649.0
Subtract 675 from 686 to get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 75

Advancing to step 6:
75 can be fit into 115 1 times, resulting in a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 6491.0
If we take 75 away from 115, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
The number 75 fits into 400 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 6491.5
Subtract 375 from 400 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
250 divided by 75 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 6491.53
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
75 goes into 250 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 6491.533
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 6491.533, and the remainder is 0.0025.
