Let's divide 743788 by 28
The aim is to understand the frequency of 28 in 743788.

On to step 1:
28 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 28

Step 2:
28 can be fit into 74 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 56 from 74 to get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 28

Moving on to step 3:
28 goes into 183 6 times with a remainder of 15.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 168 from 183 leaves us with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 28

Advancing to step 4:
28 goes into 157 5 times with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 265.0
If we subtract 140 from 157, we get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 28

Advancing to step 5:
28 can be fit into 178 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 2656.0
Subtract 168 from 178 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 28

Step 6:
108 divided by 28 is 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 26563.0
Deduct 84 from 108 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.

Advancing to step 7:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 26563.8
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.

Advancing to step 8:
When dividing 160 by 28, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 26563.85
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 26563.857
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.

Step 10:
If we divide 40 by 28, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 26563.8571
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 26563.85714
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.

Let's proceed to step 12:
If we divide 80 by 28, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 26563.857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
When dividing 240 by 28, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 26563.8571428
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.

Advancing to step 14:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 26563.85714285
If we subtract 140 from 160, we 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.

The quotient of the division is 26563.85714285, and the remainder is 2e-08.
