We divide 644465 by 27
The aim is to understand the frequency of 27 in 644465.

On to step 1:
The number 27 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 27

Going ahead to step 2:
64 divided by 27 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 54 away from 64, we end up with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 27

Going ahead to step 3:
104 divided by 27 is 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 81 away from 104, we end up with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 27

Moving on to step 4:
27 can be fit into 234 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 238.0
Deduct 216 from 234 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 27

On to step 5:
The number 27 fits into 186 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 2386.0
If we take 162 away from 186, we end up with 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 27

Going ahead to step 6:
The number 27 fits into 245 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 23869.0
Subtract 243 from 245 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
27 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 23869.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 27 fits into 200 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 23869.07
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 27 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 23869.074
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
The number 27 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 23869.074
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
27 goes into 200 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 23869.07407
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
27 can be fit into 110 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 23869.074074
If we take 108 away from 110, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 27, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 23869.074074
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
27 goes into 200 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 23869.07407407
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 23869.07407407 with a balance of 1.1e-08.
