We divide 109309 by 35
We're looking to find how many times 35 goes into 109309.

Going ahead to step 1:
If we divide 1 by 35, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 35

Let's proceed to step 2:
The number 35 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 35

On to step 3:
If we divide 109 by 35, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 105 from 109 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 35

Step 4:
35 goes into 43 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 35 from 43 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 35

Moving on to step 5:
If we divide 80 by 35, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 312.0
Subtract 70 from 80 to get 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 35

Advancing to step 6:
109 divided by 35 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3123.0
If we subtract 105 from 109, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
35 goes into 40 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 3123.1
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 35, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 3123.11
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.

The final outcome is 3123.11, with a leftover of 0.015.
