We divide 80975170 by 499
We want to figure out the number of times 80975170 can be divided by 499.

Moving on to step 1:
499 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 499

Step 2:
The number 499 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 499

Going ahead to step 3:
499 goes into 809 1 times with a remainder of 310.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 499 from 809 leaves us with 310.
Fetch the next digit (7) from the dividend, attach it to 310 and continue: 3107 / 499

Let's proceed to step 4:
3107 divided by 499 is 6 with a remainder of 113.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 2994 from 3107 to get 113.
Append the next digit (5) from the dividend to 113 and continue with: 1135 / 499

On to step 5:
1135 divided by 499 is 2 with a remainder of 137.
Use 2 as the next digit of our solution. 
Result so far: 162.0
Subtract 998 from 1135 to get 137.
Include the next digit (1) from the dividend after 137, then repeat: 1371 / 499

Moving on to step 6:
499 can be fit into 1371 2 times, resulting in a remainder of 373.
The next digit of our result is 2. 
Result so far: 1622.0
Subtract 998 from 1371 to get 373.
Include the next digit (7) from the dividend after 373, then repeat: 3737 / 499

Moving on to step 7:
If we divide 3737 by 499, we get 7 and a remainder of 244.
Record the quotient 7 as the next digit in the result. 
Result so far: 16227.0
Subtracting 3493 from 3737 leaves us with 244.
Take the next digit (0) from the dividend and append it to 244, then repeat: 2440 / 499

Going ahead to step 8:
499 can be fit into 2440 4 times, resulting in a remainder of 444.
Write down 4 as next digit of the result. 
Result so far: 162274.0
The remainder is 444 after subtracting 1996 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 9:
499 can be fit into 4440 8 times, resulting in a remainder of 448.
The next digit of our result is 8. 
Result so far: 162274.8
If we subtract 3992 from 4440, we 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.

Going ahead to step 10:
499 can be fit into 4480 8 times, resulting in a remainder of 488.
Record the quotient 8 as the next digit in the result. 
Result so far: 162274.88
Deduct 3992 from 4480 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 162274.88 with a remainder of 0.488.
