We're dividing 402815 by 55 
The aim is to understand the frequency of 55 in 402815.

Let's proceed to step 1:
If we divide 4 by 55, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 55

Let's proceed to step 2:
The number 55 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 55

Let's proceed to step 3:
55 goes into 402 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 385 from 402 to get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 55

Let's proceed to step 4:
When dividing 178 by 55, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Deduct 165 from 178 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 55

Moving on to step 5:
55 can be fit into 131 2 times, resulting in a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 732.0
The remainder is 21 after subtracting 110 from 131.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 55

Moving on to step 6:
215 divided by 55 is 3 with a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 7323.0
Deduct 165 from 215 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
If we divide 500 by 55, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 7323.9
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7323.9
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
55 can be fit into 500 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 7323.909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 7323.909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
The number 55 fits into 500 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 7323.90909
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
When dividing 50 by 55, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7323.90909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
If we divide 500 by 55, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 7323.9090909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
55 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 7323.9090909
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 7323.9090909 with a remainder of 5e-08.
