We divide 640844 by 75
We want to figure out the number of times 640844 can be divided by 75.

Going ahead 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
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 75

On to step 2:
If we divide 64 by 75, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 75

Let's proceed to step 3:
When dividing 640 by 75, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 600 from 640, we get 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 75

Moving on to step 4:
75 goes into 408 5 times with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 33 after subtracting 375 from 408.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 75

On to step 5:
334 divided by 75 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 854.0
Subtracting 300 from 334 leaves us with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 75

Advancing to step 6:
75 goes into 344 4 times with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 8544.0
The remainder is 44 after subtracting 300 from 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
440 divided by 75 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 8544.5
The remainder is 65 after subtracting 375 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
75 can be fit into 650 8 times, resulting in a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 8544.58
If we take 600 away from 650, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 8544.586
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
When dividing 500 by 75, we get 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 8544.5866
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 8544.5866 with a remaining 0.0005.
