We divide 350997 by 3
Let's see how many times 3 fits into 350997.

Advancing to step 1:
3 goes into 3 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 3 from 3.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Going ahead to step 2:
5 divided by 3 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 3 from 5, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 3

Moving on to step 3:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Subtracting 18 from 20 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Step 4:
If we divide 29 by 3, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1169.0
Subtract 27 from 29 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

On to step 5:
If we divide 29 by 3, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 11699.0
Subtract 27 from 29 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 3

Advancing to step 6:
27 divided by 3 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 116999.0
The remainder is 0 after subtracting 27 from 27.
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:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 116999.0
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.

Advancing to step 8:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 116999.0
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 116999.0 with a balance of 0.0.
