346040 ÷ 1 
Our goal is to divide 346040 by 1.

Step 1:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 3 from 3 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

On to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Going ahead to step 3:
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: 346.0
If we subtract 6 from 6, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Step 4:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3460.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 5:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 34604.0
Subtract 4 from 4 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 346040.0
The remainder is 0 after subtracting 0 from 0.
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:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 346040.0
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.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 346040.0
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.

The final outcome is 346040.0, with a leftover of 0.0.
