We're dividing 309307 by 35 
Let's see how many times 35 fits into 309307.

Step 1:
When dividing 3 by 35, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 35

Advancing to step 2:
35 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 35

Step 3:
35 goes into 309 8 times with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 280 from 309 to get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 35

Advancing to step 4:
When dividing 293 by 35, we get 8 with a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 88.0
If we take 280 away from 293, we end up with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 35

Moving on to step 5:
35 can be fit into 130 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 883.0
If we subtract 105 from 130, we get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 35

Let's proceed to step 6:
35 can be fit into 257 7 times, resulting in a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 8837.0
Deduct 245 from 257 and we're left 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.

Advancing to step 7:
35 can be fit into 120 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 8837.3
Deduct 105 from 120 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 35, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 8837.34
Subtracting 140 from 150 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 35 is 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 8837.342
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
If we divide 300 by 35, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 8837.3428
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 35, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 8837.34285
Deduct 175 from 200 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
If we divide 250 by 35, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 8837.342857
Deduct 245 from 250 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
When dividing 50 by 35, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 8837.3428571
Deduct 35 from 50 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
If we divide 150 by 35, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 8837.34285714
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 8837.34285714 and a remainder of 1e-08.
