342446 ÷ 1 
Our goal is to divide 342446 by 1.

Let's proceed to step 1:
3 divided by 1 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

On to step 2:
If we divide 4 by 1, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 0 after subtracting 4 from 4.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Let's proceed to step 3:
2 divided by 1 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 342.0
The remainder is 0 after subtracting 2 from 2.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Step 4:
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: 3424.0
Subtract 4 from 4 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Going ahead to step 5:
When dividing 4 by 1, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 34244.0
Subtract 4 from 4 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Going ahead to step 6:
6 divided by 1 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 342446.0
The remainder is 0 after subtracting 6 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 342446.0
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.

Moving on to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 342446.0
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 342446.0 with a remaining 0.0.
