We're dividing 30478729 by 100 
Let's see how many times 100 fits into 30478729.

Going ahead to step 1:
When dividing 3 by 100, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 100

Advancing to step 2:
30 divided by 100 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 100

Let's proceed to step 3:
100 can be fit into 304 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 300 from 304, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 100

Moving on to step 4:
If we divide 47 by 100, we get 0 and a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 47, we get 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 100

Moving on to step 5:
478 divided by 100 is 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 304.0
Subtract 400 from 478 to get 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 100

Step 6:
100 goes into 787 7 times with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 3047.0
The remainder is 87 after subtracting 700 from 787.
Fetch the next digit (2) from the dividend, attach it to 87 and continue: 872 / 100

Step 7:
100 can be fit into 872 8 times, resulting in a remainder of 72.
The next digit of our result is 8. 
Result so far: 30478.0
If we take 800 away from 872, we end up with 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 100

Let's proceed to step 8:
The number 100 fits into 729 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 304787.0
The remainder is 29 after subtracting 700 from 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 9:
100 can be fit into 290 2 times, resulting in a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 304787.2
Subtract 200 from 290 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
100 goes into 900 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 304787.29
Subtract 900 from 900 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.

Step 11:
When dividing 0 by 100, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 304787.29
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.

Step 12:
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: 304787.29
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 304787.29, with a leftover of 0.0.
