62807885 ÷ 804 
The aim is to understand the frequency of 804 in 62807885.

Moving on to step 1:
If we divide 6 by 804, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 804

Going ahead to step 2:
804 can be fit into 62 0 times, resulting in a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 804

Step 3:
804 goes into 628 0 times with a remainder of 628.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 628 leaves us with 628.
Append the next digit (0) from the dividend to 628 and continue with: 6280 / 804

Let's proceed to step 4:
6280 divided by 804 is 7 with a remainder of 652.
The next digit of our result is 7. 
Result so far: 7.0
If we take 5628 away from 6280, we end up with 652.
Include the next digit (7) from the dividend after 652, then repeat: 6527 / 804

Advancing to step 5:
804 can be fit into 6527 8 times, resulting in a remainder of 95.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtracting 6432 from 6527 leaves us with 95.
Include the next digit (8) from the dividend after 95, then repeat: 958 / 804

Let's proceed to step 6:
When dividing 958 by 804, we get 1 with a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 781.0
Deduct 804 from 958 and we're left with 154.
Take the next digit (8) from the dividend and append it to 154, then repeat: 1548 / 804

On to step 7:
When dividing 1548 by 804, we get 1 with a remainder of 744.
Record the quotient 1 as the next digit in the result. 
Result so far: 7811.0
If we take 804 away from 1548, we end up with 744.
Take the next digit (5) from the dividend and append it to 744, then repeat: 7445 / 804

Going ahead to step 8:
804 goes into 7445 9 times with a remainder of 209.
Use 9 as the next digit of our solution. 
Result so far: 78119.0
If we subtract 7236 from 7445, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 9:
2090 divided by 804 is 2 with a remainder of 482.
Write down 2 as next digit of the result. 
Result so far: 78119.2
Subtract 1608 from 2090 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 10:
4820 divided by 804 is 5 with a remainder of 800.
Put 5 as the next digit of the answer. 
Result so far: 78119.25
Deduct 4020 from 4820 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 11:
8000 divided by 804 is 9 with a remainder of 764.
Use 9 as the next digit of our solution. 
Result so far: 78119.259
Deduct 7236 from 8000 and we're left with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

On to step 12:
804 goes into 7640 9 times with a remainder of 404.
Use 9 as the next digit of our solution. 
Result so far: 78119.2599
Subtract 7236 from 7640 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

After the division, we end up with 78119.2599 and a remainder of 0.00404.
