We divide 349389 by 1
Let's see how many times 1 fits into 349389.

On to step 1:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Let's proceed 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
If we take 4 away from 4, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

On to step 3:
1 goes into 9 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 349.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Going ahead to step 4:
When dividing 3 by 1, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3493.0
Deduct 3 from 3 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Moving on to step 5:
8 divided by 1 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 34938.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Let's proceed to step 6:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 349389.0
If we subtract 9 from 9, 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.

Step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 349389.0
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.

Going ahead to step 8:
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: 349389.0
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.

After the division, we end up with 349389.0 and a remainder of 0.0.
