988511 divided by 28 
The aim is to understand the frequency of 28 in 988511.

Moving on to step 1:
When dividing 9 by 28, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 28

Step 2:
28 goes into 98 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 84 from 98, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 28

Advancing to step 3:
If we divide 148 by 28, we get 5 and a remainder of 8.
The next digit of our result is 5. 
Result so far: 35.0
If we take 140 away from 148, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 28

Going ahead to step 4:
28 goes into 85 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 353.0
Deduct 84 from 85 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 28

Step 5:
28 goes into 11 0 times with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 3530.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 28

Let's proceed to step 6:
111 divided by 28 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 35303.0
If we subtract 84 from 111, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 28, we get 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 35303.9
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
180 divided by 28 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 35303.96
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 35303.964
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
28 goes into 80 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 35303.9642
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 35303.96428
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 35303.964285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 35303.9642857
If we take 196 away from 200, we end up 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:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 35303.96428571
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 35303.96428571, with a leftover of 1.2e-08.
