Let's divide 78123308 by 100
We want to divide 78123308 by 100.

On to step 1:
100 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 100

Going ahead to step 2:
78 divided by 100 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 100

On to step 3:
100 can be fit into 781 7 times, resulting in a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 700 from 781 leaves us with 81.
Grab the next digit (2) from the dividend, add it to 81, then carry on: 812 / 100

Advancing to step 4:
If we divide 812 by 100, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtract 800 from 812 to get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 100

Advancing to step 5:
The number 100 fits into 123 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 781.0
If we subtract 100 from 123, we get 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 100

Step 6:
233 divided by 100 is 2 with a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 7812.0
The remainder is 33 after subtracting 200 from 233.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 100

Let's proceed to step 7:
330 divided by 100 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 78123.0
If we take 300 away from 330, we end up with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 100

Moving on to step 8:
When dividing 308 by 100, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 781233.0
Deduct 300 from 308 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 100, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 781233.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
If we divide 800 by 100, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 781233.08
If we subtract 800 from 800, 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.

Let's proceed to step 11:
0 divided by 100 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 781233.08
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.

Advancing to step 12:
0 divided by 100 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 781233.08
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.

In conclusion, the division gives 781233.08 with a balance of 0.0.
