Let's divide 668649 by 75
We want to divide 668649 by 75.

Moving on to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 75

Step 2:
75 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 75

Advancing to step 3:
If we divide 668 by 75, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 600 away from 668, we end up with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 75

On to step 4:
75 can be fit into 686 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtract 675 from 686 to get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 75

Advancing to step 5:
If we divide 114 by 75, we get 1 and a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 891.0
If we take 75 away from 114, we end up with 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 75

Going ahead to step 6:
75 goes into 399 5 times with a remainder of 24.
Write down 5 as next digit of the result. 
Result so far: 8915.0
If we take 375 away from 399, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
The number 75 fits into 240 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 8915.3
Subtract 225 from 240 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 75, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 8915.32
Subtract 150 from 150 to 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.
The next digit of our result is 0. 
Result so far: 8915.32
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.

Going ahead to step 10:
0 divided by 75 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8915.32
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.

After the division, we end up with 8915.32 and a remainder of 0.0.
