Let's divide 666658 by 75
Let's see how many times 75 fits into 666658.

Step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 75

Going ahead to step 2:
If we divide 66 by 75, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 75

Moving on to step 3:
The number 75 fits into 666 8 times, leaving a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 600 from 666 to get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 75

Going ahead to step 4:
666 divided by 75 is 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtracting 600 from 666 leaves us with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 75

Moving on to step 5:
75 goes into 665 8 times with a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 888.0
The remainder is 65 after subtracting 600 from 665.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 75

Step 6:
75 can be fit into 658 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 8888.0
If we subtract 600 from 658, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
580 divided by 75 is 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 8888.7
The remainder is 55 after subtracting 525 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
75 goes into 550 7 times with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 8888.77
If we take 525 away from 550, we end up 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.

After the division, we end up with 8888.77 and a remainder of 0.025.
