We divide 517261 by 27
The aim is to understand the frequency of 27 in 517261.

On to step 1:
5 divided by 27 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 27

Step 2:
27 goes into 51 1 times with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 24 after subtracting 27 from 51.
Bring next digit (7) of the dividend behind the 24 and repeat the process: 247 / 27

On to step 3:
The number 27 fits into 247 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 243 from 247 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 27

Advancing to step 4:
The number 27 fits into 42 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 191.0
Subtract 27 from 42 to get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 27

Going ahead to step 5:
156 divided by 27 is 5 with a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 1915.0
Subtract 135 from 156 to get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 27

Step 6:
27 goes into 211 7 times with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 19157.0
If we take 189 away from 211, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
If we divide 220 by 27, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 19157.8
If we subtract 216 from 220, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
27 can be fit into 40 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 19157.81
If we subtract 27 from 40, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
When dividing 130 by 27, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 19157.814
Deduct 108 from 130 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
27 can be fit into 220 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 19157.8148
Subtract 216 from 220 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
27 goes into 40 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 19157.81481
Subtract 27 from 40 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
When dividing 130 by 27, we get 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 19157.814814
If we take 108 away from 130, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
27 goes into 220 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 19157.8148148
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
40 divided by 27 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 19157.81481481
Subtracting 27 from 40 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 19157.81481481 with a remainder of 1.3e-08.
