We're dividing 550980 by 40 
We're looking to find how many times 40 goes into 550980.

Moving on to step 1:
If we divide 5 by 40, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 40

Going ahead to step 2:
The number 40 fits into 55 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 40 from 55, we get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 40

Step 3:
40 goes into 150 3 times with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 120 from 150 leaves us with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 40

Going ahead to step 4:
40 goes into 309 7 times with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 137.0
If we take 280 away from 309, we end up with 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 40

Step 5:
40 can be fit into 298 7 times, resulting in a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 1377.0
The remainder is 18 after subtracting 280 from 298.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 40

On to step 6:
If we divide 180 by 40, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 13774.0
If we take 160 away from 180, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 13774.5
If we take 200 away from 200, we end up 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 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13774.5
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.

Going ahead to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13774.5
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.

Our division results in 13774.5 with a remaining 0.0.
