28861536 divided by 820 
The aim is to understand the frequency of 820 in 28861536.

Moving on to step 1:
When dividing 2 by 820, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 820

Let's proceed to step 2:
820 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 820

Going ahead to step 3:
288 divided by 820 is 0 with a remainder of 288.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 288 and we're left with 288.
Take the next digit (6) from the dividend and append it to 288, then repeat: 2886 / 820

Step 4:
2886 divided by 820 is 3 with a remainder of 426.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 2460 from 2886 to get 426.
Include the next digit (1) from the dividend after 426, then repeat: 4261 / 820

On to step 5:
The number 820 fits into 4261 5 times, leaving a remainder of 161.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 4100 from 4261 and we're left with 161.
Bring next digit (5) of the dividend behind the 161 and repeat the process: 1615 / 820

Step 6:
When dividing 1615 by 820, we get 1 with a remainder of 795.
Put 1 as the next digit of the answer. 
Result so far: 351.0
Deduct 820 from 1615 and we're left with 795.
Include the next digit (3) from the dividend after 795, then repeat: 7953 / 820

Going ahead to step 7:
The number 820 fits into 7953 9 times, leaving a remainder of 573.
Put 9 as the next digit of the answer. 
Result so far: 3519.0
If we subtract 7380 from 7953, we get 573.
Take the next digit (6) from the dividend and append it to 573, then repeat: 5736 / 820

Moving on to step 8:
820 goes into 5736 6 times with a remainder of 816.
Put 6 as the next digit of the answer. 
Result so far: 35196.0
If we take 4920 away from 5736, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Going ahead to step 9:
If we divide 8160 by 820, we get 9 and a remainder of 780.
Write down 9 as next digit of the result. 
Result so far: 35196.9
Deduct 7380 from 8160 and we're left 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 10:
When dividing 7800 by 820, we get 9 with a remainder of 420.
Put 9 as the next digit of the answer. 
Result so far: 35196.99
Subtracting 7380 from 7800 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 35196.99 with a balance of 0.42.
