We look at the division of 309398 by 35 
Let's see how many times 35 fits into 309398.

Let's proceed to step 1:
3 divided by 35 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 35

Going ahead to step 2:
35 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 35

On to step 3:
When dividing 309 by 35, we get 8 with a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 280 away from 309, we end up with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 35

Moving on to step 4:
35 can be fit into 293 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we subtract 280 from 293, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 35

Advancing to step 5:
35 goes into 139 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 883.0
If we subtract 105 from 139, we get 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 35

On to step 6:
348 divided by 35 is 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 8839.0
The remainder is 33 after subtracting 315 from 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
35 goes into 330 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 8839.9
Deduct 315 from 330 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.

Advancing to step 8:
When dividing 150 by 35, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 8839.94
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
35 goes into 100 2 times with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 8839.942
Deduct 70 from 100 and we're left with 30.
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:
35 can be fit into 300 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8839.9428
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 35 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 8839.94285
If we take 175 away from 200, we end up 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.

Moving on to step 12:
250 divided by 35 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 8839.942857
If we take 245 away from 250, we end up 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.

Going ahead to step 13:
When dividing 50 by 35, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 8839.9428571
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.

Going ahead to step 14:
150 divided by 35 is 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 8839.94285714
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 8839.94285714, with a leftover of 1e-08.
