We're dividing 28548235 by 556 
The aim is to understand the frequency of 556 in 28548235.

Let's proceed to step 1:
If we divide 2 by 556, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 556

Step 2:
28 divided by 556 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 556

On to step 3:
The number 556 fits into 285 0 times, leaving a remainder of 285.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 285 to get 285.
Include the next digit (4) from the dividend after 285, then repeat: 2854 / 556

Moving on to step 4:
556 goes into 2854 5 times with a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 2780 from 2854, we get 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 556

Advancing to step 5:
The number 556 fits into 748 1 times, leaving a remainder of 192.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 556 away from 748, we end up with 192.
Include the next digit (2) from the dividend after 192, then repeat: 1922 / 556

Moving on to step 6:
The number 556 fits into 1922 3 times, leaving a remainder of 254.
The next digit of our result is 3. 
Result so far: 513.0
The remainder is 254 after subtracting 1668 from 1922.
Include the next digit (3) from the dividend after 254, then repeat: 2543 / 556

Advancing to step 7:
The number 556 fits into 2543 4 times, leaving a remainder of 319.
The number 4 becomes the next digit in our result. 
Result so far: 5134.0
Subtracting 2224 from 2543 leaves us with 319.
Take the next digit (5) from the dividend and append it to 319, then repeat: 3195 / 556

Let's proceed to step 8:
If we divide 3195 by 556, we get 5 and a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 51345.0
If we subtract 2780 from 3195, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
The number 556 fits into 4150 7 times, leaving a remainder of 258.
The number 7 becomes the next digit in our result. 
Result so far: 51345.7
If we subtract 3892 from 4150, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 10:
When dividing 2580 by 556, we get 4 with a remainder of 356.
The number 4 becomes the next digit in our result. 
Result so far: 51345.74
Deduct 2224 from 2580 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 11:
The number 556 fits into 3560 6 times, leaving a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 51345.746
If we subtract 3336 from 3560, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
556 goes into 2240 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 51345.7464
Subtracting 2224 from 2240 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:
If we divide 160 by 556, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 51345.7464
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
When dividing 1600 by 556, we get 2 with a remainder of 488.
Use 2 as the next digit of our solution. 
Result so far: 51345.746402
Subtract 1112 from 1600 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 15:
4880 divided by 556 is 8 with a remainder of 432.
The number 8 becomes the next digit in our result. 
Result so far: 51345.7464028
If we take 4448 away from 4880, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 16:
556 goes into 4320 7 times with a remainder of 428.
Put 7 as the next digit of the answer. 
Result so far: 51345.74640287
The remainder is 428 after subtracting 3892 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The quotient of the division is 51345.74640287, and the remainder is 4.28e-07.
