We're dividing 549793 by 45 
We're looking to find how many times 45 goes into 549793.

Let's proceed to step 1:
45 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 45

On to step 2:
When dividing 54 by 45, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 54, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 45

On to step 3:
45 can be fit into 99 2 times, resulting in a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 90 from 99 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 45

On to step 4:
The number 45 fits into 97 2 times, leaving a remainder of 7.
The next digit of our result is 2. 
Result so far: 122.0
Subtract 90 from 97 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 45

Step 5:
45 can be fit into 79 1 times, resulting in a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1221.0
If we subtract 45 from 79, we get 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 45

Let's proceed to step 6:
When dividing 343 by 45, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 12217.0
Subtract 315 from 343 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
45 can be fit into 280 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 12217.6
The remainder is 10 after subtracting 270 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12217.62
If we subtract 90 from 100, we 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.

Let's proceed to step 9:
45 goes into 100 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 12217.622
Subtracting 90 from 100 leaves us with 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 12217.622 with a remaining 0.001.
