We look at the division of 43454997 by 100 
We want to divide 43454997 by 100.

Going ahead to step 1:
When dividing 4 by 100, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 100

On to step 2:
If we divide 43 by 100, we get 0 and a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 100

Step 3:
100 goes into 434 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 400 away from 434, we end up with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 100

Let's proceed to step 4:
The number 100 fits into 345 3 times, leaving a remainder of 45.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 45 after subtracting 300 from 345.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 100

Going ahead to step 5:
If we divide 454 by 100, we get 4 and a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
Subtract 400 from 454 to get 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 100

Going ahead to step 6:
When dividing 549 by 100, we get 5 with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 4345.0
Deduct 500 from 549 and we're left with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 100

Step 7:
100 goes into 499 4 times with a remainder of 99.
Use 4 as the next digit of our solution. 
Result so far: 43454.0
If we take 400 away from 499, we end up with 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 100

Let's proceed to step 8:
997 divided by 100 is 9 with a remainder of 97.
The next digit of our result is 9. 
Result so far: 434549.0
The remainder is 97 after subtracting 900 from 997.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
When dividing 970 by 100, we get 9 with a remainder of 70.
The next digit of our result is 9. 
Result so far: 434549.9
If we subtract 900 from 970, 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.

Advancing to step 10:
100 goes into 700 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 434549.97
The remainder is 0 after subtracting 700 from 700.
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 11:
100 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 434549.97
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.

Step 12:
The number 100 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 434549.97
Deduct 0 from 0 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.

The final outcome is 434549.97, with a leftover of 0.0.
