664894 ÷ 75 
We want to divide 664894 by 75.

Going ahead to step 1:
The number 75 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 75

Step 2:
When dividing 66 by 75, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 75

Step 3:
When dividing 664 by 75, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 600 from 664, we get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 75

Step 4:
75 goes into 648 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we take 600 away from 648, we end up with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 75

Moving on to step 5:
If we divide 489 by 75, we get 6 and a remainder of 39.
The next digit of our result is 6. 
Result so far: 886.0
Subtracting 450 from 489 leaves us with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 75

Step 6:
75 can be fit into 394 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 8865.0
If we subtract 375 from 394, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
75 goes into 190 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 8865.2
If we take 150 away from 190, 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.

Going ahead to step 8:
400 divided by 75 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8865.25
The remainder is 25 after subtracting 375 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 8865.253
If we take 225 away from 250, 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.

Going ahead to step 10:
75 goes into 250 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 8865.2533
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.

Our division results in 8865.2533 with a remaining 0.00025.
