Let's divide 666089 by 28
The aim is to understand the frequency of 28 in 666089.

Step 1:
28 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 28

On to step 2:
If we divide 66 by 28, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 56 from 66, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 28

On to step 3:
If we divide 106 by 28, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 84 from 106 leaves us with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 28

Step 4:
220 divided by 28 is 7 with a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 237.0
Deduct 196 from 220 and we're left with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 28

Going ahead to step 5:
28 can be fit into 248 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 2378.0
Subtracting 224 from 248 leaves us with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 28

Advancing to step 6:
249 divided by 28 is 8 with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 23788.0
If we take 224 away from 249, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
The number 28 fits into 250 8 times, leaving a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 23788.8
Subtracting 224 from 250 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
28 goes into 260 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 23788.89
If we subtract 252 from 260, 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.

Moving on to step 9:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 23788.892
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.

On to step 10:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 23788.8928
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.

Let's proceed to step 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 23788.89285
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.

Going ahead to step 12:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 23788.892857
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.

Moving on to step 13:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 23788.8928571
Deduct 28 from 40 and we're left 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.

Moving on to step 14:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 23788.89285714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 23788.89285714 with a balance of 8e-09.
