Let's divide 443367 by 28
The aim is to understand the frequency of 28 in 443367.

Advancing to step 1:
4 divided by 28 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 28

On to step 2:
When dividing 44 by 28, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 28 from 44, we get 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 28

Going ahead to step 3:
The number 28 fits into 163 5 times, leaving a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 140 away from 163, we end up with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 28

Advancing to step 4:
233 divided by 28 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtract 224 from 233 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 28

Going ahead to step 5:
28 goes into 96 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 1583.0
Deduct 84 from 96 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 28

Moving on to step 6:
127 divided by 28 is 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 15834.0
Subtracting 112 from 127 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
When dividing 150 by 28, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 15834.5
Subtracting 140 from 150 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
28 goes into 100 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 15834.53
Deduct 84 from 100 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.

Advancing to step 9:
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: 15834.535
If we take 140 away from 160, we end up 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.

On to step 10:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 15834.5357
Subtract 196 from 200 to 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.

Let's proceed to step 11:
40 divided by 28 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 15834.53571
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 12:
120 divided by 28 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 15834.535714
Subtracting 112 from 120 leaves us 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.

Going ahead to step 13:
When dividing 80 by 28, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 15834.5357142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
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: 15834.53571428
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.

After the division, we end up with 15834.53571428 and a remainder of 1.6e-08.
