640747 divided by 75 
We're looking to find how many times 75 goes into 640747.

Advancing to step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 75

Advancing to step 2:
75 can be fit into 64 0 times, resulting in a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 75

Going ahead to step 3:
The number 75 fits into 640 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 8.0
If we take 600 away from 640, we end up with 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 75

Advancing to step 4:
When dividing 407 by 75, we get 5 with a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 375 away from 407, we end up with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 75

Let's proceed to step 5:
When dividing 324 by 75, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 854.0
The remainder is 24 after subtracting 300 from 324.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 75

On to step 6:
The number 75 fits into 247 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 8543.0
Subtracting 225 from 247 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
If we divide 220 by 75, we get 2 and a remainder of 70.
The next digit of our result is 2. 
Result so far: 8543.2
If we subtract 150 from 220, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
If we divide 700 by 75, we get 9 and a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 8543.29
If we take 675 away from 700, 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.

Let's proceed to step 9:
250 divided by 75 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 8543.293
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.

Step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 8543.2933
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.

In conclusion, the division gives 8543.2933 with a balance of 0.00025.
