546678 ÷ 75 
Let's see how many times 75 fits into 546678.

Step 1:
If we divide 5 by 75, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 75

Moving on to step 2:
The number 75 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 75

Advancing to step 3:
75 goes into 546 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 525 from 546 and we're left with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 75

Going ahead to step 4:
216 divided by 75 is 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 66 after subtracting 150 from 216.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 75

Step 5:
75 goes into 667 8 times with a remainder of 67.
The next digit of our result is 8. 
Result so far: 728.0
Subtract 600 from 667 to get 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 75

Moving on to step 6:
The number 75 fits into 678 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 7289.0
Subtract 675 from 678 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
75 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 7289.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
If we divide 300 by 75, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 7289.04
If we subtract 300 from 300, 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.

Let's proceed to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7289.04
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 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7289.04
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.

After the division, we end up with 7289.04 and a remainder of 0.0.
