We look at the division of 664144 by 75 
We want to divide 664144 by 75.

Moving on to step 1:
75 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 75

On to step 2:
75 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 75

Going ahead to step 3:
75 can be fit into 664 8 times, resulting in a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 64 after subtracting 600 from 664.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 75

Moving on to step 4:
The number 75 fits into 641 8 times, leaving a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we take 600 away from 641, we end up with 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 75

Advancing to step 5:
If we divide 414 by 75, we get 5 and a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 885.0
The remainder is 39 after subtracting 375 from 414.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 75

On to step 6:
75 can be fit into 394 5 times, resulting in a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 8855.0
Subtract 375 from 394 to 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.
Write down 2 as next digit of the result. 
Result so far: 8855.2
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.

Let's proceed to step 8:
When dividing 400 by 75, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 8855.25
If we take 375 away from 400, 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.

Moving on to step 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 8855.253
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
250 divided by 75 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 8855.2533
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 8855.2533, with a leftover of 0.00025.
