We divide 309590 by 27
The aim is to understand the frequency of 27 in 309590.

Moving on to step 1:
The number 27 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 27

Step 2:
The number 27 fits into 30 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 27 from 30, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 27

Moving on to step 3:
39 divided by 27 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 27 from 39 and we're left with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 27

On to step 4:
125 divided by 27 is 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtracting 108 from 125 leaves us with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 27

Going ahead to step 5:
When dividing 179 by 27, we get 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 1146.0
If we subtract 162 from 179, we get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 27

Going ahead to step 6:
27 goes into 170 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 11466.0
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 27, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 11466.2
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
When dividing 260 by 27, we get 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 11466.29
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
27 goes into 170 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11466.296
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 27, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 11466.2962
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
27 can be fit into 260 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 11466.29629
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
27 goes into 170 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 11466.296296
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
The number 27 fits into 80 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 11466.2962962
Subtracting 54 from 80 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
27 can be fit into 260 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 11466.29629629
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 11466.29629629 and a remainder of 1.7e-08.
