We look at the division of 100309 by 55 
Let's see how many times 55 fits into 100309.

Advancing to step 1:
55 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 55

Advancing to step 2:
The number 55 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 55

Let's proceed to step 3:
100 divided by 55 is 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 55 from 100 leaves us with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 55

Step 4:
The number 55 fits into 453 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 440 from 453 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 55

Advancing to step 5:
55 can be fit into 130 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 182.0
Deduct 110 from 130 and we're left with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 55

Going ahead to step 6:
209 divided by 55 is 3 with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 1823.0
Subtracting 165 from 209 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
55 goes into 440 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1823.8
Deduct 440 from 440 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.

On to step 8:
The number 55 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1823.8
Subtracting 0 from 0 leaves us 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 9:
If we divide 0 by 55, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1823.8
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.

Our division results in 1823.8 with a remaining 0.0.
