18318426 ÷ 309 
We want to figure out the number of times 18318426 can be divided by 309.

Step 1:
1 divided by 309 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 309

Let's proceed to step 2:
309 can be fit into 18 0 times, resulting in a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 309

On to step 3:
The number 309 fits into 183 0 times, leaving a remainder of 183.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 183, we get 183.
Fetch the next digit (1) from the dividend, attach it to 183 and continue: 1831 / 309

Let's proceed to step 4:
309 goes into 1831 5 times with a remainder of 286.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 1545 from 1831, we get 286.
Include the next digit (8) from the dividend after 286, then repeat: 2868 / 309

Going ahead to step 5:
2868 divided by 309 is 9 with a remainder of 87.
The next digit of our result is 9. 
Result so far: 59.0
Subtract 2781 from 2868 to get 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 309

On to step 6:
When dividing 874 by 309, we get 2 with a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 592.0
Subtract 618 from 874 to get 256.
Include the next digit (2) from the dividend after 256, then repeat: 2562 / 309

Going ahead to step 7:
309 can be fit into 2562 8 times, resulting in a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 5928.0
Subtracting 2472 from 2562 leaves us with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 309

On to step 8:
If we divide 906 by 309, we get 2 and a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 59282.0
The remainder is 288 after subtracting 618 from 906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 9:
If we divide 2880 by 309, we get 9 and a remainder of 99.
The next digit of our result is 9. 
Result so far: 59282.9
Subtract 2781 from 2880 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 10:
The number 309 fits into 990 3 times, leaving a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 59282.93
Deduct 927 from 990 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 11:
309 goes into 630 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 59282.932
If we take 618 away from 630, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
120 divided by 309 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 59282.932
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
If we divide 1200 by 309, we get 3 and a remainder of 273.
Use 3 as the next digit of our solution. 
Result so far: 59282.93203
Deduct 927 from 1200 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Advancing to step 14:
309 can be fit into 2730 8 times, resulting in a remainder of 258.
Write down 8 as next digit of the result. 
Result so far: 59282.932038
Deduct 2472 from 2730 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 15:
309 can be fit into 2580 8 times, resulting in a remainder of 108.
The number 8 becomes the next digit in our result. 
Result so far: 59282.9320388
Deduct 2472 from 2580 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

In conclusion, the division gives 59282.9320388 with a balance of 1.08e-06.
