171558 divided by 27 
The aim is to understand the frequency of 27 in 171558.

Advancing to step 1:
1 divided by 27 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 27

On to step 2:
If we divide 17 by 27, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 27

Moving on to step 3:
27 goes into 171 6 times with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 162 from 171, we get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 27

Let's proceed to step 4:
27 can be fit into 95 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtract 81 from 95 to get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 27

Advancing to step 5:
27 can be fit into 145 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 635.0
If we take 135 away from 145, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 27

Moving on to step 6:
If we divide 108 by 27, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 6354.0
Deduct 108 from 108 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 27 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6354.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 27 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6354.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6354.0, with a leftover of 0.0.
