We divide 643068 by 75
Our goal is to divide 643068 by 75.

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

Going ahead to step 2:
The number 75 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (3) from the dividend, add it to 64, then carry on: 643 / 75

Let's proceed to step 3:
If we divide 643 by 75, we get 8 and a remainder of 43.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 600 from 643, we get 43.
Fetch the next digit (0) from the dividend, attach it to 43 and continue: 430 / 75

Moving on to step 4:
The number 75 fits into 430 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 55 after subtracting 375 from 430.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 75

Going ahead to step 5:
The number 75 fits into 556 7 times, leaving a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 857.0
If we take 525 away from 556, we end up with 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 75

Going ahead to step 6:
75 goes into 318 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 8574.0
If we subtract 300 from 318, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
The number 75 fits into 180 2 times, leaving a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 8574.2
Deduct 150 from 180 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 75, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 8574.24
Deduct 300 from 300 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8574.24
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8574.24
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 8574.24 with a balance of 0.0.
