Let's divide 42431652 by 309
Our goal is to divide 42431652 by 309.

Step 1:
309 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 309

Moving on to step 2:
309 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 309

On to step 3:
If we divide 424 by 309, we get 1 and a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 309 away from 424, we end up with 115.
Take the next digit (3) from the dividend and append it to 115, then repeat: 1153 / 309

Going ahead to step 4:
1153 divided by 309 is 3 with a remainder of 226.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 927 from 1153 leaves us with 226.
Append the next digit (1) from the dividend to 226 and continue with: 2261 / 309

Going ahead to step 5:
The number 309 fits into 2261 7 times, leaving a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 2163 from 2261 to get 98.
Include the next digit (6) from the dividend after 98, then repeat: 986 / 309

Step 6:
If we divide 986 by 309, we get 3 and a remainder of 59.
The number 3 becomes the next digit in our result. 
Result so far: 1373.0
Subtracting 927 from 986 leaves us with 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 309

Moving on to step 7:
When dividing 595 by 309, we get 1 with a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 13731.0
Subtract 309 from 595 to get 286.
Fetch the next digit (2) from the dividend, attach it to 286 and continue: 2862 / 309

Going ahead to step 8:
If we divide 2862 by 309, we get 9 and a remainder of 81.
The next digit of our result is 9. 
Result so far: 137319.0
If we subtract 2781 from 2862, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 9:
309 can be fit into 810 2 times, resulting in a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 137319.2
Subtracting 618 from 810 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 10:
The number 309 fits into 1920 6 times, leaving a remainder of 66.
The next digit of our result is 6. 
Result so far: 137319.26
Subtracting 1854 from 1920 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
The number 309 fits into 660 2 times, leaving a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 137319.262
Deduct 618 from 660 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
If we divide 420 by 309, we get 1 and a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 137319.2621
If we subtract 309 from 420, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 13:
When dividing 1110 by 309, we get 3 with a remainder of 183.
The next digit of our result is 3. 
Result so far: 137319.26213
Subtracting 927 from 1110 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 14:
1830 divided by 309 is 5 with a remainder of 285.
The next digit of our result is 5. 
Result so far: 137319.262135
If we subtract 1545 from 1830, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 15:
2850 divided by 309 is 9 with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 137319.2621359
If we take 2781 away from 2850, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 16:
The number 309 fits into 690 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 137319.26213592
Subtracting 618 from 690 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 137319.26213592, and the remainder is 7.2e-08.
