We divide 87328968 by 643
Our goal is to divide 87328968 by 643.

Let's proceed to step 1:
643 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 643

Moving on to step 2:
When dividing 87 by 643, we get 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 643

Let's proceed to step 3:
873 divided by 643 is 1 with a remainder of 230.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 643 from 873 leaves us with 230.
Bring next digit (2) of the dividend behind the 230 and repeat the process: 2302 / 643

On to step 4:
If we divide 2302 by 643, we get 3 and a remainder of 373.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1929 from 2302 and we're left with 373.
Bring next digit (8) of the dividend behind the 373 and repeat the process: 3738 / 643

Let's proceed to step 5:
3738 divided by 643 is 5 with a remainder of 523.
The next digit of our result is 5. 
Result so far: 135.0
The remainder is 523 after subtracting 3215 from 3738.
Fetch the next digit (9) from the dividend, attach it to 523 and continue: 5239 / 643

Advancing to step 6:
643 goes into 5239 8 times with a remainder of 95.
Record the quotient 8 as the next digit in the result. 
Result so far: 1358.0
If we subtract 5144 from 5239, we get 95.
Grab the next digit (6) from the dividend, add it to 95, then carry on: 956 / 643

Going ahead to step 7:
643 goes into 956 1 times with a remainder of 313.
Write down 1 as next digit of the result. 
Result so far: 13581.0
If we subtract 643 from 956, we get 313.
Include the next digit (8) from the dividend after 313, then repeat: 3138 / 643

Moving on to step 8:
The number 643 fits into 3138 4 times, leaving a remainder of 566.
Write down 4 as next digit of the result. 
Result so far: 135814.0
If we subtract 2572 from 3138, we get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 9:
The number 643 fits into 5660 8 times, leaving a remainder of 516.
The number 8 becomes the next digit in our result. 
Result so far: 135814.8
Subtract 5144 from 5660 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Step 10:
The number 643 fits into 5160 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 135814.88
If we subtract 5144 from 5160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 135814.88, and the remainder is 0.016.
