438430 divided by 27 
The aim is to understand the frequency of 27 in 438430.

Advancing to step 1:
When dividing 4 by 27, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 27

Going ahead to step 2:
43 divided by 27 is 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 27 from 43 leaves us with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 27

Advancing to step 3:
168 divided by 27 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 162 from 168, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 27

Let's proceed to step 4:
If we divide 64 by 27, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 162.0
If we take 54 away from 64, we end up with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 27

Going ahead to step 5:
27 goes into 103 3 times with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 1623.0
Subtracting 81 from 103 leaves us with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 27

Advancing to step 6:
27 can be fit into 220 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 16238.0
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
If we divide 40 by 27, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 16238.1
The remainder is 13 after subtracting 27 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
If we divide 130 by 27, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 16238.14
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.

Let's proceed to step 9:
The number 27 fits into 220 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 16238.148
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 10:
The number 27 fits into 40 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 16238.1481
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.

Moving on to step 11:
If we divide 130 by 27, we get 4 and a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 16238.14814
The remainder is 22 after subtracting 108 from 130.
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 12:
220 divided by 27 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 16238.148148
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 13:
27 goes into 40 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 16238.1481481
Deduct 27 from 40 and we're left 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.

Step 14:
27 can be fit into 130 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 16238.14814814
The remainder is 22 after subtracting 108 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 16238.14814814, and the remainder is 2.2e-08.
