45288775 ÷ 816 
Let's see how many times 816 fits into 45288775.

Going ahead to step 1:
The number 816 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 816

On to step 2:
816 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 816

Step 3:
If we divide 452 by 816, we get 0 and a remainder of 452.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 452 leaves us with 452.
Append the next digit (8) from the dividend to 452 and continue with: 4528 / 816

Let's proceed to step 4:
4528 divided by 816 is 5 with a remainder of 448.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4080 from 4528 and we're left with 448.
Include the next digit (8) from the dividend after 448, then repeat: 4488 / 816

Advancing to step 5:
The number 816 fits into 4488 5 times, leaving a remainder of 408.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtract 4080 from 4488 to get 408.
Append the next digit (7) from the dividend to 408 and continue with: 4087 / 816

On to step 6:
816 goes into 4087 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 555.0
Deduct 4080 from 4087 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 816

Going ahead to step 7:
When dividing 77 by 816, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 5550.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (5) of the dividend behind the 77 and repeat the process: 775 / 816

Going ahead to step 8:
816 goes into 775 0 times with a remainder of 775.
Write down 0 as next digit of the result. 
Result so far: 55500.0
If we subtract 0 from 775, we get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Step 9:
When dividing 7750 by 816, we get 9 with a remainder of 406.
The number 9 becomes the next digit in our result. 
Result so far: 55500.9
Subtracting 7344 from 7750 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 10:
The number 816 fits into 4060 4 times, leaving a remainder of 796.
The number 4 becomes the next digit in our result. 
Result so far: 55500.94
Subtracting 3264 from 4060 leaves us with 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Moving on to step 11:
When dividing 7960 by 816, we get 9 with a remainder of 616.
The number 9 becomes the next digit in our result. 
Result so far: 55500.949
If we subtract 7344 from 7960, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Step 12:
When dividing 6160 by 816, we get 7 with a remainder of 448.
Record the quotient 7 as the next digit in the result. 
Result so far: 55500.9497
Subtract 5712 from 6160 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 13:
816 can be fit into 4480 5 times, resulting in a remainder of 400.
Write down 5 as next digit of the result. 
Result so far: 55500.94975
Subtract 4080 from 4480 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 14:
4000 divided by 816 is 4 with a remainder of 736.
Put 4 as the next digit of the answer. 
Result so far: 55500.949754
Subtracting 3264 from 4000 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 15:
816 goes into 7360 9 times with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 55500.9497549
If we take 7344 away from 7360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
816 can be fit into 160 0 times, resulting in a remainder of 160.
The next digit of our result is 0. 
Result so far: 55500.9497549
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 55500.9497549, with a leftover of 1.6e-07.
