986807 divided by 28 
The aim is to understand the frequency of 28 in 986807.

Let's proceed to step 1:
When dividing 9 by 28, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 28

Moving on to step 2:
28 can be fit into 98 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 84 from 98 and we're left with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 28

Step 3:
When dividing 146 by 28, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 140 from 146, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 28

Let's proceed to step 4:
When dividing 68 by 28, we get 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 352.0
Subtract 56 from 68 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 28

Going ahead to step 5:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3524.0
If we subtract 112 from 120, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 28

On to step 6:
28 goes into 87 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 35243.0
The remainder is 3 after subtracting 84 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 28, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 35243.1
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 28 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 35243.1
Subtract 0 from 20 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.

Moving on to step 9:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 35243.107
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
28 goes into 40 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 35243.1071
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 35243.10714
Subtract 112 from 120 to 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.

Step 12:
28 goes into 80 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 35243.107142
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.

Going ahead to step 13:
If we divide 240 by 28, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 35243.1071428
If we take 224 away from 240, we end up 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.

On to step 14:
If we divide 160 by 28, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 35243.10714285
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.

After the division, we end up with 35243.10714285 and a remainder of 2e-08.
