Let's divide 28104814 by 87
The aim is to understand the frequency of 87 in 28104814.

Advancing to step 1:
2 divided by 87 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 87

On to step 2:
When dividing 28 by 87, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 87

Let's proceed to step 3:
If we divide 281 by 87, we get 3 and a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 261 from 281 to get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 87

Going ahead to step 4:
87 can be fit into 200 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 26 after subtracting 174 from 200.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 87

On to step 5:
The number 87 fits into 264 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 323.0
Deduct 261 from 264 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 87

Moving on to step 6:
The number 87 fits into 38 0 times, leaving a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 3230.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 87

Moving on to step 7:
87 goes into 381 4 times with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 32304.0
Deduct 348 from 381 and we're left with 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 87

Step 8:
If we divide 334 by 87, we get 3 and a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 323043.0
Subtracting 261 from 334 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
If we divide 730 by 87, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 323043.8
Deduct 696 from 730 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
If we divide 340 by 87, we get 3 and a remainder of 79.
The next digit of our result is 3. 
Result so far: 323043.83
Subtract 261 from 340 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
790 divided by 87 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 323043.839
If we subtract 783 from 790, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
The number 87 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 323043.839
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
87 goes into 700 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 323043.83908
Subtracting 696 from 700 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
When dividing 40 by 87, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 323043.83908
If we take 0 away from 40, we end up 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 15:
87 goes into 400 4 times with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 323043.8390804
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 16:
520 divided by 87 is 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 323043.83908045
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 323043.83908045 and a remainder of 8.5e-08.
