We divide 570400 by 27
The aim is to understand the frequency of 27 in 570400.

Let's proceed to step 1:
27 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 27

Moving on to step 2:
When dividing 57 by 27, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 54 from 57 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 27

Advancing to step 3:
The number 27 fits into 30 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 27 from 30 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 27

Let's proceed to step 4:
When dividing 34 by 27, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 211.0
The remainder is 7 after subtracting 27 from 34.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 27

Going ahead to step 5:
When dividing 70 by 27, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2112.0
The remainder is 16 after subtracting 54 from 70.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 27

Step 6:
If we divide 160 by 27, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 21125.0
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
When dividing 250 by 27, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 21125.9
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
If we divide 70 by 27, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 21125.92
If we subtract 54 from 70, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
The number 27 fits into 160 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 21125.925
If we subtract 135 from 160, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
27 can be fit into 250 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 21125.9259
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
If we divide 70 by 27, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 21125.92592
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
27 goes into 160 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 21125.925925
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
27 can be fit into 250 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 21125.9259259
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
If we divide 70 by 27, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 21125.92592592
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 21125.92592592, with a leftover of 1.6e-08.
