We divide 704444 by 28
The aim is to understand the frequency of 28 in 704444.

Going ahead to step 1:
If we divide 7 by 28, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 28

Moving on to step 2:
When dividing 70 by 28, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 56 away from 70, we end up with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 28

Advancing to step 3:
The number 28 fits into 144 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 4 after subtracting 140 from 144.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 28

Let's proceed to step 4:
28 goes into 44 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
The remainder is 16 after subtracting 28 from 44.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 28

On to step 5:
When dividing 164 by 28, we get 5 with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 2515.0
Subtracting 140 from 164 leaves us with 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 28

Moving on to step 6:
The number 28 fits into 244 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 25158.0
Subtracting 224 from 244 leaves us 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 7:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 25158.7
The remainder is 4 after subtracting 196 from 200.
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 8:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 25158.71
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 9:
120 divided by 28 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 25158.714
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 10:
28 goes into 80 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 25158.7142
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.

Advancing to step 11:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25158.71428
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.

On to step 12:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 25158.714285
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.

Moving on to step 13:
28 goes into 200 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 25158.7142857
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.

Going ahead to step 14:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 25158.71428571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 25158.71428571, with a leftover of 1.2e-08.
