Let's divide 40309 by 55
We're looking to find how many times 55 goes into 40309.

Going ahead to step 1:
The number 55 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 55

Going ahead to step 2:
55 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 55

On to step 3:
If we divide 403 by 55, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 18 after subtracting 385 from 403.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 55

Let's proceed to step 4:
180 divided by 55 is 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 15 after subtracting 165 from 180.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 55

Going ahead to step 5:
The number 55 fits into 159 2 times, leaving a remainder of 49.
Write down 2 as next digit of the result. 
Result so far: 732.0
Deduct 110 from 159 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 6:
55 can be fit into 490 8 times, resulting in a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 732.8
Subtract 440 from 490 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
500 divided by 55 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 732.89
Subtracting 495 from 500 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 732.89
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
55 goes into 500 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 732.8909
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
If we divide 50 by 55, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 732.8909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
55 goes into 500 9 times with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 732.890909
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
If we divide 50 by 55, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 732.890909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 732.89090909
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 732.89090909 with a remaining 5e-09.
