621916 ÷ 27 
The aim is to understand the frequency of 27 in 621916.

Let's proceed to step 1:
27 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 27

Moving on to step 2:
If we divide 62 by 27, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 54 from 62, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 27

Going ahead to step 3:
The number 27 fits into 81 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 0 after subtracting 81 from 81.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 27

Step 4:
When dividing 9 by 27, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 230.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 27

On to step 5:
The number 27 fits into 91 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 2303.0
If we take 81 away from 91, we end up with 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 27

Let's proceed to step 6:
27 goes into 106 3 times with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 23033.0
Deduct 81 from 106 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
250 divided by 27 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 23033.9
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
If we divide 70 by 27, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 23033.92
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 27 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 23033.925
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
250 divided by 27 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 23033.9259
Subtracting 243 from 250 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
When dividing 70 by 27, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 23033.92592
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
160 divided by 27 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 23033.925925
If we subtract 135 from 160, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
When dividing 250 by 27, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 23033.9259259
If we subtract 243 from 250, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
The number 27 fits into 70 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 23033.92592592
If we subtract 54 from 70, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 23033.92592592, and the remainder is 1.6e-08.
