45080090 divided by 542 
We want to figure out the number of times 45080090 can be divided by 542.

Step 1:
When dividing 4 by 542, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 542

Moving on to step 2:
When dividing 45 by 542, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 542

Going ahead to step 3:
The number 542 fits into 450 0 times, leaving a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 450, we get 450.
Append the next digit (8) from the dividend to 450 and continue with: 4508 / 542

Let's proceed to step 4:
When dividing 4508 by 542, we get 8 with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 4336 away from 4508, we end up with 172.
Include the next digit (0) from the dividend after 172, then repeat: 1720 / 542

Let's proceed to step 5:
The number 542 fits into 1720 3 times, leaving a remainder of 94.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 1626 from 1720 leaves us with 94.
Take the next digit (0) from the dividend and append it to 94, then repeat: 940 / 542

Let's proceed to step 6:
If we divide 940 by 542, we get 1 and a remainder of 398.
Use 1 as the next digit of our solution. 
Result so far: 831.0
The remainder is 398 after subtracting 542 from 940.
Append the next digit (9) from the dividend to 398 and continue with: 3989 / 542

Moving on to step 7:
542 can be fit into 3989 7 times, resulting in a remainder of 195.
The next digit of our result is 7. 
Result so far: 8317.0
Subtracting 3794 from 3989 leaves us with 195.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 542

On to step 8:
When dividing 1950 by 542, we get 3 with a remainder of 324.
Write down 3 as next digit of the result. 
Result so far: 83173.0
If we take 1626 away from 1950, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 9:
If we divide 3240 by 542, we get 5 and a remainder of 530.
Record the quotient 5 as the next digit in the result. 
Result so far: 83173.5
Deduct 2710 from 3240 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 10:
When dividing 5300 by 542, we get 9 with a remainder of 422.
The number 9 becomes the next digit in our result. 
Result so far: 83173.59
If we take 4878 away from 5300, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Let's proceed to step 11:
542 can be fit into 4220 7 times, resulting in a remainder of 426.
Put 7 as the next digit of the answer. 
Result so far: 83173.597
If we take 3794 away from 4220, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

On to step 12:
The number 542 fits into 4260 7 times, leaving a remainder of 466.
Put 7 as the next digit of the answer. 
Result so far: 83173.5977
Deduct 3794 from 4260 and we're left with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

In conclusion, the division gives 83173.5977 with a balance of 0.00466.
