We divide 12977392 by 100
Our goal is to divide 12977392 by 100.

Step 1:
100 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 100

Going ahead to step 2:
If we divide 12 by 100, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 100

On to step 3:
129 divided by 100 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 100 from 129 to get 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 100

Advancing to step 4:
100 goes into 297 2 times with a remainder of 97.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 200 from 297 to get 97.
Include the next digit (7) from the dividend after 97, then repeat: 977 / 100

Step 5:
The number 100 fits into 977 9 times, leaving a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we take 900 away from 977, we end up with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 100

Step 6:
773 divided by 100 is 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 1297.0
Subtracting 700 from 773 leaves us with 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 100

Let's proceed to step 7:
100 goes into 739 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 12977.0
If we subtract 700 from 739, we get 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 100

On to step 8:
100 can be fit into 392 3 times, resulting in a remainder of 92.
The next digit of our result is 3. 
Result so far: 129773.0
If we take 300 away from 392, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 9:
920 divided by 100 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 129773.9
If we subtract 900 from 920, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
200 divided by 100 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 129773.92
Subtract 200 from 200 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.

Advancing to step 11:
If we divide 0 by 100, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 129773.92
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.

Step 12:
If we divide 0 by 100, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 129773.92
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 129773.92 and a remainder of 0.0.
