30305921 ÷ 500 
We want to figure out the number of times 30305921 can be divided by 500.

On to step 1:
3 divided by 500 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 500

Step 2:
30 divided by 500 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 500

Let's proceed to step 3:
The number 500 fits into 303 0 times, leaving a remainder of 303.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 303 and we're left with 303.
Take the next digit (0) from the dividend and append it to 303, then repeat: 3030 / 500

Let's proceed to step 4:
The number 500 fits into 3030 6 times, leaving a remainder of 30.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 3000 from 3030 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 500

On to step 5:
500 goes into 305 0 times with a remainder of 305.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtracting 0 from 305 leaves us with 305.
Fetch the next digit (9) from the dividend, attach it to 305 and continue: 3059 / 500

Moving on to step 6:
When dividing 3059 by 500, we get 6 with a remainder of 59.
Write down 6 as next digit of the result. 
Result so far: 606.0
If we subtract 3000 from 3059, we get 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 500

On to step 7:
If we divide 592 by 500, we get 1 and a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 6061.0
Subtracting 500 from 592 leaves us with 92.
Bring next digit (1) of the dividend behind the 92 and repeat the process: 921 / 500

Going ahead to step 8:
500 goes into 921 1 times with a remainder of 421.
The number 1 becomes the next digit in our result. 
Result so far: 60611.0
If we take 500 away from 921, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 9:
When dividing 4210 by 500, we get 8 with a remainder of 210.
The next digit of our result is 8. 
Result so far: 60611.8
The remainder is 210 after subtracting 4000 from 4210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
500 goes into 2100 4 times with a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 60611.84
The remainder is 100 after subtracting 2000 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
The number 500 fits into 1000 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 60611.842
If we take 1000 away from 1000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
0 divided by 500 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 60611.842
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
500 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 60611.842
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 60611.842 with a remainder of 0.0.
