We're dividing 31405589 by 27 
The aim is to understand the frequency of 27 in 31405589.

Step 1:
The number 27 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 27

Step 2:
When dividing 31 by 27, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 27 from 31 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 27

Moving on to step 3:
If we divide 44 by 27, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 27 away from 44, we end up with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 27

Going ahead to step 4:
The number 27 fits into 170 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtracting 162 from 170 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 27

Let's proceed to step 5:
27 can be fit into 85 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 1163.0
If we take 81 away from 85, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 27

Moving on to step 6:
45 divided by 27 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 11631.0
Subtracting 27 from 45 leaves us with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 27

Let's proceed to step 7:
27 goes into 188 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 116316.0
Subtracting 162 from 188 leaves us with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 27

Moving on to step 8:
When dividing 269 by 27, we get 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 1163169.0
Subtracting 243 from 269 leaves us 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 9:
If we divide 260 by 27, we get 9 and a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 1163169.9
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 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: 1163169.96
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.

Advancing to step 11:
80 divided by 27 is 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 1163169.962
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:
260 divided by 27 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 1163169.9629
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.

Step 13:
27 goes into 170 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 1163169.96296
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.

Advancing to step 14:
80 divided by 27 is 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 1163169.962962
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.

Step 15:
If we divide 260 by 27, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 1163169.9629629
Deduct 243 from 260 and we're left 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.

Moving on to step 16:
The number 27 fits into 170 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 1163169.96296296
Subtract 162 from 170 to 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.

The quotient of the division is 1163169.96296296, and the remainder is 8e-09.
