12786217 ÷ 100 
We want to figure out the number of times 12786217 can be divided by 100.

On to step 1:
If we divide 1 by 100, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 100

Let's proceed 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
Subtract 0 from 12 to get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 100

Let's proceed to step 3:
100 goes into 127 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 100 from 127 leaves us with 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 100

Advancing to step 4:
The number 100 fits into 278 2 times, leaving a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 200 from 278 to get 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 100

Advancing to step 5:
100 goes into 786 7 times with a remainder of 86.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Subtract 700 from 786 to get 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 100

Going ahead to step 6:
862 divided by 100 is 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 1278.0
If we take 800 away from 862, we end up with 62.
Bring next digit (1) of the dividend behind the 62 and repeat the process: 621 / 100

Advancing to step 7:
100 goes into 621 6 times with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 12786.0
Subtracting 600 from 621 leaves us with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 100

Step 8:
When dividing 217 by 100, we get 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 127862.0
Subtracting 200 from 217 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
If we divide 170 by 100, we get 1 and a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 127862.1
Subtracting 100 from 170 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
700 divided by 100 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 127862.17
Subtract 700 from 700 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:
The number 100 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 127862.17
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.

Step 12:
100 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 127862.17
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.

In conclusion, the division gives 127862.17 with a balance of 0.0.
