We look at the division of 173658 by 55 
The aim is to understand the frequency of 55 in 173658.

Moving on to step 1:
55 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 55

Going ahead to step 2:
17 divided by 55 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 55

Moving on to step 3:
If we divide 173 by 55, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 165 from 173 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 55

Step 4:
If we divide 86 by 55, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 55 from 86 and we're left with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 55

Moving on to step 5:
When dividing 315 by 55, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 315.0
If we subtract 275 from 315, we get 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 55

Advancing to step 6:
408 divided by 55 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 3157.0
Subtracting 385 from 408 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 55 fits into 230 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 3157.4
If we take 220 away from 230, we end up 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.

On to step 8:
The number 55 fits into 100 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 3157.41
If we subtract 55 from 100, we get 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 9:
If we divide 450 by 55, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 3157.418
Subtract 440 from 450 to 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.

On to step 10:
If we divide 100 by 55, we get 1 and a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 3157.4181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 3157.41818
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.

Moving on to step 12:
If we divide 100 by 55, we get 1 and a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 3157.418181
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 13:
55 can be fit into 450 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 3157.4181818
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.

Going ahead to step 14:
100 divided by 55 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 3157.41818181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 3157.41818181, with a leftover of 4.5e-08.
