45307290 ÷ 88 
Our goal is to divide 45307290 by 88.

On to step 1:
88 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 88

On to step 2:
88 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 88

On to step 3:
88 goes into 453 5 times with a remainder of 13.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 440 from 453 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 88

On to step 4:
88 can be fit into 130 1 times, resulting in a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 88 away from 130, we end up with 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 88

Step 5:
88 can be fit into 427 4 times, resulting in a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 514.0
If we take 352 away from 427, we end up with 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 88

Let's proceed to step 6:
The number 88 fits into 752 8 times, leaving a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 5148.0
If we take 704 away from 752, we end up with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 88

On to step 7:
489 divided by 88 is 5 with a remainder of 49.
The next digit of our result is 5. 
Result so far: 51485.0
Subtract 440 from 489 to get 49.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 88

On to step 8:
88 can be fit into 490 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 514855.0
Deduct 440 from 490 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
88 can be fit into 500 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 514855.5
Subtracting 440 from 500 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 88, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 514855.56
Subtract 528 from 600 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
88 goes into 720 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 514855.568
Subtracting 704 from 720 leaves us 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.

Moving on to step 12:
160 divided by 88 is 1 with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 514855.5681
Subtract 88 from 160 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
88 goes into 720 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 514855.56818
The remainder is 16 after subtracting 704 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
The number 88 fits into 160 1 times, leaving a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 514855.568181
Subtracting 88 from 160 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 15:
When dividing 720 by 88, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 514855.5681818
If we take 704 away from 720, 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.

Advancing to step 16:
88 goes into 160 1 times with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 514855.56818181
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 514855.56818181 with a remainder of 7.2e-08.
