We're dividing 40690311 by 309 
We're looking to find how many times 309 goes into 40690311.

Step 1:
309 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 309

Advancing to step 2:
309 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 309

Advancing to step 3:
If we divide 406 by 309, we get 1 and a remainder of 97.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 309 from 406, we get 97.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 309

Let's proceed to step 4:
309 can be fit into 979 3 times, resulting in a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 52 after subtracting 927 from 979.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 309

Moving on to step 5:
When dividing 520 by 309, we get 1 with a remainder of 211.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
The remainder is 211 after subtracting 309 from 520.
Append the next digit (3) from the dividend to 211 and continue with: 2113 / 309

Moving on to step 6:
309 can be fit into 2113 6 times, resulting in a remainder of 259.
Record the quotient 6 as the next digit in the result. 
Result so far: 1316.0
If we subtract 1854 from 2113, we get 259.
Include the next digit (1) from the dividend after 259, then repeat: 2591 / 309

Advancing to step 7:
309 can be fit into 2591 8 times, resulting in a remainder of 119.
The next digit of our result is 8. 
Result so far: 13168.0
Subtracting 2472 from 2591 leaves us with 119.
Include the next digit (1) from the dividend after 119, then repeat: 1191 / 309

Let's proceed to step 8:
1191 divided by 309 is 3 with a remainder of 264.
Record the quotient 3 as the next digit in the result. 
Result so far: 131683.0
Subtract 927 from 1191 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 9:
When dividing 2640 by 309, we get 8 with a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 131683.8
Subtract 2472 from 2640 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 10:
The number 309 fits into 1680 5 times, leaving a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 131683.85
If we subtract 1545 from 1680, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
The number 309 fits into 1350 4 times, leaving a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 131683.854
Subtract 1236 from 1350 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 12:
If we divide 1140 by 309, we get 3 and a remainder of 213.
Put 3 as the next digit of the answer. 
Result so far: 131683.8543
Subtracting 927 from 1140 leaves us with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 13:
2130 divided by 309 is 6 with a remainder of 276.
Put 6 as the next digit of the answer. 
Result so far: 131683.85436
If we subtract 1854 from 2130, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 14:
When dividing 2760 by 309, we get 8 with a remainder of 288.
The next digit of our result is 8. 
Result so far: 131683.854368
The remainder is 288 after subtracting 2472 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 15:
The number 309 fits into 2880 9 times, leaving a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 131683.8543689
Subtracting 2781 from 2880 leaves us with 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 16:
If we divide 990 by 309, we get 3 and a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 131683.85436893
The remainder is 63 after subtracting 927 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 131683.85436893 with a remainder of 6.3e-08.
