We're dividing 548462 by 45 
We want to figure out the number of times 548462 can be divided by 45.

Let's proceed to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 45

Moving on to step 2:
The number 45 fits into 54 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 45 from 54 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 45

On to step 3:
If we divide 98 by 45, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 8 after subtracting 90 from 98.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 45

Let's proceed to step 4:
When dividing 84 by 45, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 121.0
The remainder is 39 after subtracting 45 from 84.
Take the next digit (6) from the dividend and append it to 39, then repeat: 396 / 45

Moving on to step 5:
45 goes into 396 8 times with a remainder of 36.
The next digit of our result is 8. 
Result so far: 1218.0
Subtract 360 from 396 to get 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 45

Moving on to step 6:
362 divided by 45 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 12188.0
If we take 360 away from 362, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 45 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12188.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 12188.04
The remainder is 20 after subtracting 180 from 200.
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 9:
When dividing 200 by 45, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 12188.044
Subtracting 180 from 200 leaves us 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.

After the division, we end up with 12188.044 and a remainder of 0.002.
