900575 ÷ 27 
The aim is to understand the frequency of 27 in 900575.

Step 1:
27 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 27

On to step 2:
27 goes into 90 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 81 from 90, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 27

Moving on to step 3:
27 goes into 90 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 81 away from 90, we end up with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 27

Moving on to step 4:
If we divide 95 by 27, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 333.0
Subtract 81 from 95 to get 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 27

Going ahead to step 5:
27 can be fit into 147 5 times, resulting in a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 3335.0
The remainder is 12 after subtracting 135 from 147.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 27

Going ahead to step 6:
If we divide 125 by 27, we get 4 and a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 33354.0
Subtracting 108 from 125 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.

Going ahead to step 7:
27 goes into 170 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 33354.6
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.

Advancing to step 8:
80 divided by 27 is 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 33354.62
If we subtract 54 from 80, we get 26.
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 9:
If we divide 260 by 27, we get 9 and a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 33354.629
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.

Going ahead to step 10:
27 goes into 170 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 33354.6296
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.

Advancing to step 11:
27 can be fit into 80 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 33354.62962
Deduct 54 from 80 and we're left 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 12:
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: 33354.629629
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
27 goes into 170 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 33354.6296296
If we subtract 162 from 170, we get 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 14:
If we divide 80 by 27, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 33354.62962962
Subtract 54 from 80 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 33354.62962962 with a balance of 2.6e-08.
