The number 109 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 109

Going ahead to step 2:
109 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Include the next digit (4) from the dividend after 45, then repeat: 454 / 109

Let's proceed to step 3:
109 goes into 454 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 4.0

Put 5 as the next digit of the answer. 
Result so far: 41735.0
Subtract 545 from 624 to get 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 109

Advancing to step 8:
790 divided by 109 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 417357.0
Subtracting 763 from 790 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
If we divide 270 by 109, we get 2 and a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 417357.2
The remainder is 52 after subtracting 218 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 109 is 4 with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 417357.24
Subtracting 436 from 520 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 11:

The number 7 becomes the next digit in our result. 
Result so far: 417357.247
Subtracting 763 from 840 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 12:
770 divided by 109 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 417357.2477
Subtracting 763 from 770 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 417357.2477 with a balance of 7e-05.
