640025 divided by 75 
We want to figure out the number of times 640025 can be divided by 75.

Moving on to step 1:
The number 75 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 75

Let's proceed to step 2:
75 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (0) from the dividend, add it to 64, then carry on: 640 / 75

On to step 3:
75 goes into 640 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 600 from 640, we get 40.
Bring next digit (0) of the dividend behind the 40 and repeat the process: 400 / 75

Going ahead to step 4:
The number 75 fits into 400 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 85.0
If we take 375 away from 400, we end up with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 75

Step 5:
When dividing 252 by 75, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 853.0
Deduct 225 from 252 and we're left with 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 75

Let's proceed to step 6:
When dividing 275 by 75, we get 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 8533.0
Subtract 225 from 275 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
If we divide 500 by 75, we get 6 and a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 8533.6
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
500 divided by 75 is 6 with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 8533.66
Deduct 450 from 500 and we're left 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 8533.66 with a remaining 0.05.
