574156 divided by 28 
The aim is to understand the frequency of 28 in 574156.

Advancing to step 1:
5 divided by 28 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 28

Moving on to step 2:
If we divide 57 by 28, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 56 from 57 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 28

Moving on to step 3:
When dividing 14 by 28, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 14, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 28

Moving on to step 4:
The number 28 fits into 141 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 205.0
If we take 140 away from 141, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 28

Moving on to step 5:
28 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 2050.0
Subtract 0 from 15 to get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 28

Moving on to step 6:
When dividing 156 by 28, we get 5 with a remainder of 16.
The next digit of our result is 5. 
Result so far: 20505.0
If we take 140 away from 156, 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.

Moving on to step 7:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 20505.5
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.

Let's proceed to step 8:
200 divided by 28 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 20505.57
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.

On to step 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 20505.571
Subtract 28 from 40 to 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.

Going ahead to step 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 20505.5714
If we subtract 112 from 120, 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.

Going ahead to step 11:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 20505.57142
Subtract 56 from 80 to 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.

On to step 12:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 20505.571428
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.

Moving on to step 13:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 20505.5714285
Deduct 140 from 160 and we're left 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.

Let's proceed to step 14:
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: 20505.57142857
If we subtract 196 from 200, we 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.

Our division results in 20505.57142857 with a remaining 4e-09.
