969903 ÷ 28 
The aim is to understand the frequency of 28 in 969903.

Step 1:
The number 28 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 28

Step 2:
If we divide 96 by 28, we get 3 and a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 84 from 96 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 28

Going ahead to step 3:
28 can be fit into 129 4 times, resulting in a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 112 from 129 leaves us with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 28

Step 4:
179 divided by 28 is 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 346.0
If we take 168 away from 179, we end up with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 28

On to step 5:
28 can be fit into 110 3 times, resulting in a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 3463.0
Subtract 84 from 110 to get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 28

Advancing to step 6:
263 divided by 28 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 34639.0
If we take 252 away from 263, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 28, we get 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 34639.3
If we take 84 away from 110, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
28 can be fit into 260 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 34639.39
If we subtract 252 from 260, 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 9:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 34639.392
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.

Moving on to step 10:
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: 34639.3928
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.

On to step 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 34639.39285
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.

On to step 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 34639.392857
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.

Advancing to step 13:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 34639.3928571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
If we divide 120 by 28, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 34639.39285714
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.

The quotient of the division is 34639.39285714, and the remainder is 8e-09.
