30748909 ÷ 4 
Let's see how many times 4 fits into 30748909.

Advancing to step 1:
When dividing 3 by 4, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 4

Advancing to step 2:
If we divide 30 by 4, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 28 away from 30, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 4

On to step 3:
4 can be fit into 27 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 24 from 27 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 4

Step 4:
34 divided by 4 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 768.0
If we take 32 away from 34, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 4

Going ahead to step 5:
4 goes into 28 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7687.0
Deduct 28 from 28 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 4

Let's proceed to step 6:
4 goes into 9 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 76872.0
Deduct 8 from 9 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 4

Advancing to step 7:
The number 4 fits into 10 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 768722.0
If we subtract 8 from 10, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 4

Going ahead to step 8:
4 can be fit into 29 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7687227.0
Subtract 28 from 29 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
If we divide 10 by 4, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 7687227.2
Subtract 8 from 10 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
If we divide 20 by 4, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 7687227.25
Subtracting 20 from 20 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.

Moving on to step 11:
When dividing 0 by 4, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7687227.25
Subtract 0 from 0 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.

Going ahead to step 12:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7687227.25
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 7687227.25, with a leftover of 0.0.
