Let's divide 171866 by 55
The aim is to understand the frequency of 55 in 171866.

On to step 1:
55 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 55

Step 2:
If we divide 17 by 55, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 55

Going ahead to step 3:
When dividing 171 by 55, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 165 from 171 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 55

Advancing to step 4:
68 divided by 55 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 55 from 68 to get 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 55

On to step 5:
136 divided by 55 is 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 312.0
Subtract 110 from 136 to get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 55

Going ahead to step 6:
When dividing 266 by 55, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 3124.0
The remainder is 46 after subtracting 220 from 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
460 divided by 55 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 3124.8
If we take 440 away from 460, we end up 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.

On to step 8:
The number 55 fits into 200 3 times, leaving a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 3124.83
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.

Step 9:
55 can be fit into 350 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 3124.836
If we take 330 away from 350, we end up 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.

On to step 10:
55 goes into 200 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 3124.8363
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.

Advancing to step 11:
The number 55 fits into 350 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 3124.83636
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.

Going ahead to step 12:
55 can be fit into 200 3 times, resulting in a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 3124.836363
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.

Moving on to step 13:
55 can be fit into 350 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 3124.8363636
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.

Step 14:
55 goes into 200 3 times with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 3124.83636363
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.

The quotient of the division is 3124.83636363, and the remainder is 3.5e-08.
