24609421 ÷ 306 
We're looking to find how many times 306 goes into 24609421.

Going ahead to step 1:
If we divide 2 by 306, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 306

Going ahead to step 2:
306 can be fit into 24 0 times, resulting in a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 306

On to step 3:
If we divide 246 by 306, we get 0 and a remainder of 246.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 246, we get 246.
Include the next digit (0) from the dividend after 246, then repeat: 2460 / 306

Going ahead to step 4:
When dividing 2460 by 306, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 2448 from 2460 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 306

Advancing to step 5:
The number 306 fits into 129 0 times, leaving a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we subtract 0 from 129, we get 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 306

Step 6:
306 goes into 1294 4 times with a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 804.0
If we subtract 1224 from 1294, we get 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 306

Going ahead to step 7:
The number 306 fits into 702 2 times, leaving a remainder of 90.
Write down 2 as next digit of the result. 
Result so far: 8042.0
The remainder is 90 after subtracting 612 from 702.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 306

Going ahead to step 8:
306 can be fit into 901 2 times, resulting in a remainder of 289.
Use 2 as the next digit of our solution. 
Result so far: 80422.0
If we take 612 away from 901, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 9:
When dividing 2890 by 306, we get 9 with a remainder of 136.
Record the quotient 9 as the next digit in the result. 
Result so far: 80422.9
Subtracting 2754 from 2890 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 10:
1360 divided by 306 is 4 with a remainder of 136.
Put 4 as the next digit of the answer. 
Result so far: 80422.94
Subtract 1224 from 1360 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 11:
When dividing 1360 by 306, we get 4 with a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 80422.944
Deduct 1224 from 1360 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 80422.944, with a leftover of 0.0136.
