478485 ÷ 75 
Let's see how many times 75 fits into 478485.

Going ahead to step 1:
When dividing 4 by 75, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 75

On to step 2:
When dividing 47 by 75, we get 0 with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 75

Advancing to step 3:
75 goes into 478 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 28 after subtracting 450 from 478.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 75

Moving on to step 4:
If we divide 284 by 75, we get 3 and a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
The remainder is 59 after subtracting 225 from 284.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 75

Step 5:
The number 75 fits into 598 7 times, leaving a remainder of 73.
The next digit of our result is 7. 
Result so far: 637.0
Subtracting 525 from 598 leaves us with 73.
Take the next digit (5) from the dividend and append it to 73, then repeat: 735 / 75

Let's proceed to step 6:
When dividing 735 by 75, we get 9 with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 6379.0
The remainder is 60 after subtracting 675 from 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
The number 75 fits into 600 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 6379.8
Subtracting 600 from 600 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.

Let's proceed to step 8:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 6379.8
If we subtract 0 from 0, we get 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 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6379.8
Deduct 0 from 0 and we're left 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.

After the division, we end up with 6379.8 and a remainder of 0.0.
