Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 3 from 3 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Going ahead to step 2:
1 goes into 4 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 4 from 4 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Moving on to step 3:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 345.0
Subtract 5 from 5 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Step 4:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3455.0
Subtracting 5 from 5 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Advancing to step 5:
When dividing 9 by 1, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 34559.0
Subtract 9 from 9 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Going ahead to step 6:
1 goes into 4 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 345594.0
Deduct 4 from 4 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 7:
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: 345594.0
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.

On to step 8:
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: 345594.0
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.

After the division, we end up with 345594.0 and a remainder of 0.0.
