82640543 ÷ 100 
We want to divide 82640543 by 100.

Let's proceed to step 1:
The number 100 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 100

Moving on to step 2:
The number 100 fits into 82 0 times, leaving a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 100

Step 3:
When dividing 826 by 100, we get 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 800 from 826, we get 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 100

On to step 4:
If we divide 264 by 100, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 82.0
Subtracting 200 from 264 leaves us with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 100

Moving on to step 5:
If we divide 640 by 100, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 826.0
If we take 600 away from 640, we end up with 40.
Include the next digit (5) from the dividend after 40, then repeat: 405 / 100

Going ahead to step 6:
The number 100 fits into 405 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 8264.0
If we take 400 away from 405, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 100

Going ahead to step 7:
If we divide 54 by 100, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 82640.0
The remainder is 54 after subtracting 0 from 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 100

Going ahead to step 8:
If we divide 543 by 100, we get 5 and a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 826405.0
Subtracting 500 from 543 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
The number 100 fits into 430 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 826405.4
If we take 400 away from 430, we end up 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.

Step 10:
The number 100 fits into 300 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 826405.43
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 100 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 826405.43
If we subtract 0 from 0, we 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.

Advancing to step 12:
If we divide 0 by 100, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 826405.43
If we take 0 away from 0, we end up 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.

The final outcome is 826405.43, with a leftover of 0.0.
