We divide 369923 by 28
The aim is to understand the frequency of 28 in 369923.

Advancing to step 1:
If we divide 3 by 28, we get 0 and 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.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 28

Advancing to step 2:
The number 28 fits into 36 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 28 from 36 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 28

Going ahead to step 3:
The number 28 fits into 89 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 84 from 89 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 28

Step 4:
The number 28 fits into 59 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtract 56 from 59 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 28

Going ahead to step 5:
28 goes into 32 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1321.0
Deduct 28 from 32 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 28

Advancing to step 6:
28 goes into 43 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 13211.0
If we subtract 28 from 43, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
28 goes into 150 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 13211.5
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 28, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 13211.53
Subtract 84 from 100 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.

Let's proceed to step 9:
28 goes into 160 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 13211.535
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.

Advancing to step 10:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 13211.5357
Subtracting 196 from 200 leaves us 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.

Moving on to step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 13211.53571
Subtracting 28 from 40 leaves us 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.

Going ahead to step 12:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 13211.535714
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.

Let's proceed to step 13:
If we divide 80 by 28, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 13211.5357142
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 14:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 13211.53571428
Subtracting 224 from 240 leaves us 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.

After the division, we end up with 13211.53571428 and a remainder of 1.6e-08.
