Let's divide 287450 by 55
The aim is to understand the frequency of 55 in 287450.

Moving on to step 1:
The number 55 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 55

Moving on to step 2:
If we divide 28 by 55, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 55

Going ahead to step 3:
55 goes into 287 5 times with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 275 from 287 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 55

Step 4:
55 can be fit into 124 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Subtracting 110 from 124 leaves us with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 55

On to step 5:
55 goes into 145 2 times with a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 522.0
The remainder is 35 after subtracting 110 from 145.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 55

Let's proceed to step 6:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 5226.0
Subtracting 330 from 350 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.

Advancing to step 7:
When dividing 200 by 55, we get 3 with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 5226.3
Subtracting 165 from 200 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
350 divided by 55 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 5226.36
If we subtract 330 from 350, 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.

On to step 9:
If we divide 200 by 55, we get 3 and a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 5226.363
If we subtract 165 from 200, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
If we divide 350 by 55, we get 6 and a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 5226.3636
The remainder is 20 after subtracting 330 from 350.
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 11:
200 divided by 55 is 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 5226.36363
The remainder is 35 after subtracting 165 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 55 fits into 350 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 5226.363636
Subtract 330 from 350 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 13:
If we divide 200 by 55, we get 3 and a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 5226.3636363
If we subtract 165 from 200, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 14:
When dividing 350 by 55, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 5226.36363636
Deduct 330 from 350 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.

The final result is 5226.36363636 with a remainder of 2e-08.
