28511875 divided by 818 
The aim is to understand the frequency of 818 in 28511875.

Step 1:
If we divide 2 by 818, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 818

Step 2:
If we divide 28 by 818, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 818

On to step 3:
818 goes into 285 0 times with a remainder of 285.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 285, we end up with 285.
Grab the next digit (1) from the dividend, add it to 285, then carry on: 2851 / 818

Step 4:
2851 divided by 818 is 3 with a remainder of 397.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2454 from 2851, we get 397.
Append the next digit (1) from the dividend to 397 and continue with: 3971 / 818

Moving on to step 5:
3971 divided by 818 is 4 with a remainder of 699.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtract 3272 from 3971 to get 699.
Append the next digit (8) from the dividend to 699 and continue with: 6998 / 818

Advancing to step 6:
6998 divided by 818 is 8 with a remainder of 454.
The next digit of our result is 8. 
Result so far: 348.0
Subtracting 6544 from 6998 leaves us with 454.
Append the next digit (7) from the dividend to 454 and continue with: 4547 / 818

Step 7:
818 can be fit into 4547 5 times, resulting in a remainder of 457.
The number 5 becomes the next digit in our result. 
Result so far: 3485.0
If we take 4090 away from 4547, we end up with 457.
Bring next digit (5) of the dividend behind the 457 and repeat the process: 4575 / 818

Let's proceed to step 8:
When dividing 4575 by 818, we get 5 with a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 34855.0
Subtract 4090 from 4575 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Let's proceed to step 9:
If we divide 4850 by 818, we get 5 and a remainder of 760.
Write down 5 as next digit of the result. 
Result so far: 34855.5
Subtract 4090 from 4850 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 10:
818 goes into 7600 9 times with a remainder of 238.
Use 9 as the next digit of our solution. 
Result so far: 34855.59
If we subtract 7362 from 7600, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 11:
When dividing 2380 by 818, we get 2 with a remainder of 744.
The number 2 becomes the next digit in our result. 
Result so far: 34855.592
Subtract 1636 from 2380 to get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 12:
When dividing 7440 by 818, we get 9 with a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 34855.5929
The remainder is 78 after subtracting 7362 from 7440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 13:
The number 818 fits into 780 0 times, leaving a remainder of 780.
Write down 0 as next digit of the result. 
Result so far: 34855.5929
If we take 0 away from 780, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 14:
When dividing 7800 by 818, we get 9 with a remainder of 438.
The next digit of our result is 9. 
Result so far: 34855.592909
Deduct 7362 from 7800 and we're left with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 15:
If we divide 4380 by 818, we get 5 and a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 34855.5929095
Subtract 4090 from 4380 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 16:
2900 divided by 818 is 3 with a remainder of 446.
Record the quotient 3 as the next digit in the result. 
Result so far: 34855.59290953
Deduct 2454 from 2900 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

After the division, we end up with 34855.59290953 and a remainder of 4.46e-07.
