We're dividing 573869 by 55 
The aim is to understand the frequency of 55 in 573869.

Moving on to step 1:
The number 55 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 55

Going ahead to step 2:
55 goes into 57 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 55 from 57, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 55

Step 3:
If we divide 23 by 55, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 23, we end up with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 55

On to step 4:
238 divided by 55 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Subtract 220 from 238 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 55

Step 5:
The number 55 fits into 186 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 1043.0
If we take 165 away from 186, we end up with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 55

Let's proceed to step 6:
If we divide 219 by 55, we get 3 and a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 10433.0
If we subtract 165 from 219, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
55 goes into 540 9 times with a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 10433.9
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 10433.98
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
55 goes into 100 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 10433.981
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
55 goes into 450 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 10433.9818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
55 goes into 100 1 times with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 10433.98181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
If we divide 450 by 55, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 10433.981818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
55 goes into 100 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 10433.9818181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 10433.98181818
If we subtract 440 from 450, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 10433.98181818, and the remainder is 1e-08.
