19857904 ÷ 500 
The aim is to understand the frequency of 500 in 19857904.

Going ahead to step 1:
If we divide 1 by 500, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 500

On to step 2:
If we divide 19 by 500, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 500

Moving on to step 3:
500 can be fit into 198 0 times, resulting in a remainder of 198.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 198 leaves us with 198.
Append the next digit (5) from the dividend to 198 and continue with: 1985 / 500

Moving on to step 4:
The number 500 fits into 1985 3 times, leaving a remainder of 485.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 485 after subtracting 1500 from 1985.
Fetch the next digit (7) from the dividend, attach it to 485 and continue: 4857 / 500

Going ahead to step 5:
If we divide 4857 by 500, we get 9 and a remainder of 357.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 4500 from 4857 and we're left with 357.
Include the next digit (9) from the dividend after 357, then repeat: 3579 / 500

Let's proceed to step 6:
500 can be fit into 3579 7 times, resulting in a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
The remainder is 79 after subtracting 3500 from 3579.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 500

On to step 7:
The number 500 fits into 790 1 times, leaving a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 3971.0
The remainder is 290 after subtracting 500 from 790.
Fetch the next digit (4) from the dividend, attach it to 290 and continue: 2904 / 500

On to step 8:
When dividing 2904 by 500, we get 5 with a remainder of 404.
Record the quotient 5 as the next digit in the result. 
Result so far: 39715.0
Deduct 2500 from 2904 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 9:
When dividing 4040 by 500, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 39715.8
Deduct 4000 from 4040 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
500 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 39715.8
Deduct 0 from 400 and we're left with 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 11:
The number 500 fits into 4000 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 39715.808
If we subtract 4000 from 4000, 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.

Let's proceed to step 12:
500 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39715.808
Subtracting 0 from 0 leaves us 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.

Advancing to step 13:
The number 500 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39715.808
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 quotient of the division is 39715.808, and the remainder is 0.0.
