345363 ÷ 1 
We want to divide 345363 by 1.

Step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 3 away from 3, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 4 from 4 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Advancing to step 3:
When dividing 5 by 1, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 345.0
Deduct 5 from 5 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Moving on to step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3453.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Moving on to step 5:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 34536.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Going ahead to step 6:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 345363.0
The remainder is 0 after subtracting 3 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 345363.0
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.

Going ahead to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 345363.0
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.

Our division results in 345363.0 with a remaining 0.0.
