We're dividing 733353 by 28 
The aim is to understand the frequency of 28 in 733353.

Step 1:
When dividing 7 by 28, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 28

On to step 2:
28 goes into 73 2 times with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 56 from 73, we get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 28

Moving on to step 3:
The number 28 fits into 173 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 168 from 173 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 28

Going ahead to step 4:
When dividing 53 by 28, we get 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 261.0
The remainder is 25 after subtracting 28 from 53.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 28

Advancing to step 5:
28 goes into 255 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 2619.0
If we take 252 away from 255, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 28

Moving on to step 6:
The number 28 fits into 33 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 26191.0
Subtract 28 from 33 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 28 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 26191.1
Deduct 28 from 50 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
If we divide 220 by 28, we get 7 and a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 26191.17
If we take 196 away from 220, we end up 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.

Let's proceed to step 9:
When dividing 240 by 28, we get 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 26191.178
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 10:
28 goes into 160 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 26191.1785
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.

Moving on to step 11:
When dividing 200 by 28, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 26191.17857
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.

On to step 12:
If we divide 40 by 28, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 26191.178571
If we subtract 28 from 40, we 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 13:
If we divide 120 by 28, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 26191.1785714
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.

Advancing to step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 26191.17857142
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.

After the division, we end up with 26191.17857142 and a remainder of 2.4e-08.
