402671 ÷ 27 
The aim is to understand the frequency of 27 in 402671.

Moving on to step 1:
If we divide 4 by 27, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 27

Going ahead to step 2:
40 divided by 27 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 27 from 40 leaves us with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 27

Going ahead to step 3:
27 can be fit into 132 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 24 after subtracting 108 from 132.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 27

Let's proceed to step 4:
When dividing 246 by 27, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 149.0
The remainder is 3 after subtracting 243 from 246.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 27

Moving on to step 5:
The number 27 fits into 37 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1491.0
Subtract 27 from 37 to get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 27

Moving on to step 6:
When dividing 101 by 27, we get 3 with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 14913.0
If we subtract 81 from 101, we 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.

Advancing to step 7:
200 divided by 27 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 14913.7
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.

Advancing to step 8:
27 can be fit into 110 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 14913.74
Subtract 108 from 110 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.

Moving on to step 9:
20 divided by 27 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 14913.74
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.

Going ahead to step 10:
The number 27 fits into 200 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 14913.7407
Deduct 189 from 200 and we're left 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.

Going ahead to step 11:
27 goes into 110 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 14913.74074
Deduct 108 from 110 and we're left 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.

Going ahead to step 12:
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: 14913.74074
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.

Going ahead to step 13:
27 goes into 200 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 14913.7407407
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.

Going ahead to step 14:
27 can be fit into 110 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 14913.74074074
Subtracting 108 from 110 leaves us 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.

In conclusion, the division gives 14913.74074074 with a balance of 2e-09.
