Let's divide 212509 by 27
The aim is to understand the frequency of 27 in 212509.

Moving on to step 1:
27 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 27

Let's proceed to step 2:
27 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 27

Let's proceed to step 3:
When dividing 212 by 27, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 189 from 212 and we're left with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 27

Moving on to step 4:
If we divide 235 by 27, we get 8 and a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we take 216 away from 235, we end up with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 27

Advancing to step 5:
27 can be fit into 190 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 787.0
If we take 189 away from 190, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 27

Going ahead to step 6:
27 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 7870.0
Subtract 0 from 19 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
27 goes into 190 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7870.7
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
The number 27 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7870.7
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 27, we get 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 7870.703
Subtract 81 from 100 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
The number 27 fits into 190 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7870.7037
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
If we divide 10 by 27, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 7870.7037
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 27 is 3 with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 7870.703703
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
When dividing 190 by 27, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7870.7037037
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
The number 27 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7870.7037037
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 7870.7037037 with a remaining 1e-08.
