73999999 divided by 500 
We want to figure out the number of times 73999999 can be divided by 500.

On to step 1:
When dividing 7 by 500, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 500

Step 2:
500 goes into 73 0 times with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 500

Step 3:
739 divided by 500 is 1 with a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 500 from 739 leaves us with 239.
Take the next digit (9) from the dividend and append it to 239, then repeat: 2399 / 500

On to step 4:
500 goes into 2399 4 times with a remainder of 399.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2000 from 2399 to get 399.
Include the next digit (9) from the dividend after 399, then repeat: 3999 / 500

Step 5:
500 can be fit into 3999 7 times, resulting in a remainder of 499.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Subtracting 3500 from 3999 leaves us with 499.
Bring next digit (9) of the dividend behind the 499 and repeat the process: 4999 / 500

On to step 6:
500 goes into 4999 9 times with a remainder of 499.
The number 9 becomes the next digit in our result. 
Result so far: 1479.0
Subtracting 4500 from 4999 leaves us with 499.
Grab the next digit (9) from the dividend, add it to 499, then carry on: 4999 / 500

Let's proceed to step 7:
The number 500 fits into 4999 9 times, leaving a remainder of 499.
Use 9 as the next digit of our solution. 
Result so far: 14799.0
Subtract 4500 from 4999 to get 499.
Fetch the next digit (9) from the dividend, attach it to 499 and continue: 4999 / 500

Let's proceed to step 8:
The number 500 fits into 4999 9 times, leaving a remainder of 499.
Put 9 as the next digit of the answer. 
Result so far: 147999.0
If we take 4500 away from 4999, we end up with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

On to step 9:
The number 500 fits into 4990 9 times, leaving a remainder of 490.
Write down 9 as next digit of the result. 
Result so far: 147999.9
If we take 4500 away from 4990, we end up with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 10:
The number 500 fits into 4900 9 times, leaving a remainder of 400.
The number 9 becomes the next digit in our result. 
Result so far: 147999.99
If we subtract 4500 from 4900, we 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.

The final result is 147999.99 with a remainder of 0.4.
