55086063 divided by 303 
We want to divide 55086063 by 303.

On to step 1:
If we divide 5 by 303, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 303

Going ahead to step 2:
303 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 303

Advancing to step 3:
If we divide 550 by 303, we get 1 and a remainder of 247.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 303 away from 550, we end up with 247.
Include the next digit (8) from the dividend after 247, then repeat: 2478 / 303

Moving on to step 4:
303 can be fit into 2478 8 times, resulting in a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 2424 from 2478 leaves us with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 303

Moving on to step 5:
303 goes into 546 1 times with a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 181.0
Deduct 303 from 546 and we're left with 243.
Fetch the next digit (0) from the dividend, attach it to 243 and continue: 2430 / 303

Let's proceed to step 6:
303 goes into 2430 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 1818.0
If we take 2424 away from 2430, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 303

Step 7:
303 goes into 66 0 times with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 18180.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 303

Advancing to step 8:
663 divided by 303 is 2 with a remainder of 57.
The number 2 becomes the next digit in our result. 
Result so far: 181802.0
Subtracting 606 from 663 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
303 goes into 570 1 times with a remainder of 267.
Use 1 as the next digit of our solution. 
Result so far: 181802.1
If we subtract 303 from 570, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 10:
When dividing 2670 by 303, we get 8 with a remainder of 246.
Record the quotient 8 as the next digit in the result. 
Result so far: 181802.18
Subtract 2424 from 2670 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 11:
The number 303 fits into 2460 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 181802.188
Subtract 2424 from 2460 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 181802.188 with a remaining 0.0036.
