We're dividing 359516 by 28 
The aim is to understand the frequency of 28 in 359516.

Going ahead to step 1:
When dividing 3 by 28, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 28

Step 2:
If we divide 35 by 28, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 28 from 35 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 28

Moving on to step 3:
28 can be fit into 79 2 times, resulting in a remainder of 23.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 56 from 79 and we're left with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 28

Step 4:
If we divide 235 by 28, we get 8 and a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 128.0
The remainder is 11 after subtracting 224 from 235.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 28

Step 5:
28 can be fit into 111 3 times, resulting in a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 1283.0
Deduct 84 from 111 and we're left with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 28

Moving on to step 6:
When dividing 276 by 28, we get 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 12839.0
If we subtract 252 from 276, 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.

Step 7:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 12839.8
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
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: 12839.85
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 28 fits into 200 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 12839.857
Subtract 196 from 200 to 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.

Going ahead to step 10:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 12839.8571
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.

Moving on to step 11:
When dividing 120 by 28, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 12839.85714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 12839.857142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

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: 12839.8571428
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.

Step 14:
If we divide 160 by 28, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 12839.85714285
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 12839.85714285 with a remaining 2e-08.
