353866 divided by 1 
Our goal is to divide 353866 by 1.

Going ahead to step 1:
3 divided by 1 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Let's proceed to step 2:
5 divided by 1 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 5 away from 5, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

On to step 3:
When dividing 3 by 1, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 353.0
Subtracting 3 from 3 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Moving on to step 4:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 3538.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Let's proceed to step 5:
1 goes into 6 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 35386.0
Subtracting 6 from 6 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Going ahead to step 6:
When dividing 6 by 1, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 353866.0
If we subtract 6 from 6, 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.

Going ahead to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 353866.0
Deduct 0 from 0 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.

Advancing to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 353866.0
If we take 0 away from 0, we end up 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 353866.0 with a balance of 0.0.
