Let's divide 28031585 by 555
The aim is to understand the frequency of 555 in 28031585.

Moving on to step 1:
If we divide 2 by 555, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 555

Step 2:
555 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 555

Let's proceed to step 3:
555 can be fit into 280 0 times, resulting in a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 280 and we're left with 280.
Grab the next digit (3) from the dividend, add it to 280, then carry on: 2803 / 555

Going ahead to step 4:
When dividing 2803 by 555, we get 5 with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 2775 from 2803, we get 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 555

Moving on to step 5:
555 goes into 281 0 times with a remainder of 281.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 281 after subtracting 0 from 281.
Append the next digit (5) from the dividend to 281 and continue with: 2815 / 555

Let's proceed to step 6:
555 goes into 2815 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 505.0
Subtracting 2775 from 2815 leaves us with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 555

Advancing to step 7:
555 can be fit into 408 0 times, resulting in a remainder of 408.
Use 0 as the next digit of our solution. 
Result so far: 5050.0
Subtract 0 from 408 to get 408.
Bring next digit (5) of the dividend behind the 408 and repeat the process: 4085 / 555

Moving on to step 8:
The number 555 fits into 4085 7 times, leaving a remainder of 200.
The number 7 becomes the next digit in our result. 
Result so far: 50507.0
If we take 3885 away from 4085, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 9:
The number 555 fits into 2000 3 times, leaving a remainder of 335.
The number 3 becomes the next digit in our result. 
Result so far: 50507.3
Deduct 1665 from 2000 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 10:
When dividing 3350 by 555, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 50507.36
Subtract 3330 from 3350 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.

Step 11:
If we divide 200 by 555, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 50507.36
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
If we divide 2000 by 555, we get 3 and a remainder of 335.
Record the quotient 3 as the next digit in the result. 
Result so far: 50507.3603
Subtracting 1665 from 2000 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 13:
3350 divided by 555 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 50507.36036
Subtract 3330 from 3350 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.

Moving on to step 14:
555 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 50507.36036
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 15:
The number 555 fits into 2000 3 times, leaving a remainder of 335.
Put 3 as the next digit of the answer. 
Result so far: 50507.3603603
Subtract 1665 from 2000 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 16:
When dividing 3350 by 555, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 50507.36036036
The remainder is 20 after subtracting 3330 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 50507.36036036 with a remainder of 2e-08.
