19712823 divided by 487 
The aim is to understand the frequency of 487 in 19712823.

Advancing to step 1:
When dividing 1 by 487, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 487

Moving on to step 2:
487 goes into 19 0 times with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 487

Advancing to step 3:
The number 487 fits into 197 0 times, leaving a remainder of 197.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 197 after subtracting 0 from 197.
Grab the next digit (1) from the dividend, add it to 197, then carry on: 1971 / 487

Let's proceed to step 4:
If we divide 1971 by 487, we get 4 and a remainder of 23.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1948 from 1971 and we're left with 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 487

Step 5:
232 divided by 487 is 0 with a remainder of 232.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 232 and we're left with 232.
Append the next digit (8) from the dividend to 232 and continue with: 2328 / 487

Going ahead to step 6:
487 goes into 2328 4 times with a remainder of 380.
Put 4 as the next digit of the answer. 
Result so far: 404.0
If we take 1948 away from 2328, we end up with 380.
Take the next digit (2) from the dividend and append it to 380, then repeat: 3802 / 487

Moving on to step 7:
If we divide 3802 by 487, we get 7 and a remainder of 393.
The number 7 becomes the next digit in our result. 
Result so far: 4047.0
If we subtract 3409 from 3802, we get 393.
Take the next digit (3) from the dividend and append it to 393, then repeat: 3933 / 487

Step 8:
3933 divided by 487 is 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 40478.0
Deduct 3896 from 3933 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
370 divided by 487 is 0 with a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 40478.0
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 10:
When dividing 3700 by 487, we get 7 with a remainder of 291.
Write down 7 as next digit of the result. 
Result so far: 40478.07
Subtract 3409 from 3700 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 11:
487 can be fit into 2910 5 times, resulting in a remainder of 475.
Use 5 as the next digit of our solution. 
Result so far: 40478.075
Subtracting 2435 from 2910 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

On to step 12:
If we divide 4750 by 487, we get 9 and a remainder of 367.
The next digit of our result is 9. 
Result so far: 40478.0759
If we take 4383 away from 4750, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 13:
The number 487 fits into 3670 7 times, leaving a remainder of 261.
The next digit of our result is 7. 
Result so far: 40478.07597
If we subtract 3409 from 3670, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 14:
The number 487 fits into 2610 5 times, leaving a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 40478.075975
The remainder is 175 after subtracting 2435 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 15:
487 can be fit into 1750 3 times, resulting in a remainder of 289.
The next digit of our result is 3. 
Result so far: 40478.0759753
If we take 1461 away from 1750, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 16:
487 goes into 2890 5 times with a remainder of 455.
The number 5 becomes the next digit in our result. 
Result so far: 40478.07597535
If we take 2435 away from 2890, we end up with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

The final result is 40478.07597535 with a remainder of 4.55e-07.
