200980 ÷ 45 
Let's see how many times 45 fits into 200980.

Moving on to step 1:
45 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 45

Moving on to step 2:
If we divide 20 by 45, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 45

On to step 3:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 20 after subtracting 180 from 200.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 45

Going ahead to step 4:
The number 45 fits into 209 4 times, leaving a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtracting 180 from 209 leaves us with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 45

Step 5:
If we divide 298 by 45, we get 6 and a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 446.0
Deduct 270 from 298 and we're left with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 45

Moving on to step 6:
The number 45 fits into 280 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 4466.0
Subtract 270 from 280 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
45 can be fit into 100 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 4466.2
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 45, we get 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 4466.22
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 4466.22 with a remaining 0.01.
