We're dividing 343785 by 39 
Our goal is to divide 343785 by 39.

Advancing to step 1:
39 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 39

Step 2:
39 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 39

Moving on to step 3:
39 can be fit into 343 8 times, resulting in a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 312 from 343 to get 31.
Bring next digit (7) of the dividend behind the 31 and repeat the process: 317 / 39

Let's proceed to step 4:
If we divide 317 by 39, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtract 312 from 317 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 39

Let's proceed to step 5:
The number 39 fits into 58 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 881.0
The remainder is 19 after subtracting 39 from 58.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 39

Let's proceed to step 6:
39 can be fit into 195 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8815.0
Deduct 195 from 195 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
If we divide 0 by 39, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8815.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
39 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8815.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 8815.0 with a balance of 0.0.
