994429 ÷ 28 
The aim is to understand the frequency of 28 in 994429.

Let's proceed to step 1:
9 divided by 28 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 28

Let's proceed to step 2:
The number 28 fits into 99 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 84 away from 99, we end up with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 28

Moving on to step 3:
If we divide 154 by 28, we get 5 and a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Deduct 140 from 154 and we're left with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 28

Going ahead to step 4:
28 can be fit into 144 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 355.0
Subtracting 140 from 144 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 28

Moving on to step 5:
28 goes into 42 1 times with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 3551.0
The remainder is 14 after subtracting 28 from 42.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 28

Advancing to step 6:
28 can be fit into 149 5 times, resulting in a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 35515.0
The remainder is 9 after subtracting 140 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 divided by 28 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 35515.3
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
28 goes into 60 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 35515.32
The remainder is 4 after subtracting 56 from 60.
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 9:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 35515.321
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 10:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 35515.3214
If we take 112 away from 120, we end up 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.

On to step 11:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 35515.32142
Subtracting 56 from 80 leaves us 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.

Going ahead to step 12:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 35515.321428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 35515.3214285
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.

Moving on to step 14:
200 divided by 28 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 35515.32142857
Deduct 196 from 200 and we're left 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.

After the division, we end up with 35515.32142857 and a remainder of 4e-09.
