120310 ÷ 55 
The aim is to understand the frequency of 55 in 120310.

Advancing to step 1:
1 divided by 55 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 55

Step 2:
When dividing 12 by 55, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 55

On to step 3:
The number 55 fits into 120 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 110 from 120 leaves us with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 55

Advancing to step 4:
55 goes into 103 1 times with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 55 from 103 leaves us with 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 55

Advancing to step 5:
55 goes into 481 8 times with a remainder of 41.
The next digit of our result is 8. 
Result so far: 218.0
If we take 440 away from 481, we end up with 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 55

Moving on to step 6:
If we divide 410 by 55, we get 7 and a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 2187.0
If we subtract 385 from 410, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
When dividing 250 by 55, we get 4 with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 2187.4
If we subtract 220 from 250, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 55, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 2187.45
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
55 goes into 250 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 2187.454
Subtracting 220 from 250 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
55 goes into 300 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 2187.4545
If we take 275 away from 300, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
55 can be fit into 250 4 times, resulting in a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 2187.45454
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
300 divided by 55 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2187.454545
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 13:
55 goes into 250 4 times with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 2187.4545454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
55 goes into 300 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 2187.45454545
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 2187.45454545 with a remaining 2.5e-08.
