20251978 ÷ 27 
The aim is to understand the frequency of 27 in 20251978.

On to step 1:
When dividing 2 by 27, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 27

On to step 2:
If we divide 20 by 27, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 27

Step 3:
202 divided by 27 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 189 from 202 and we're left with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 27

On to step 4:
The number 27 fits into 135 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 75.0
The remainder is 0 after subtracting 135 from 135.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 27

Let's proceed to step 5:
If we divide 1 by 27, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 750.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 27

On to step 6:
If we divide 19 by 27, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 7500.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 27

Moving on to step 7:
197 divided by 27 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 75007.0
If we subtract 189 from 197, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 27

Moving on to step 8:
If we divide 88 by 27, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 750073.0
Deduct 81 from 88 and we're left 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.

Step 9:
27 can be fit into 70 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 750073.2
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 27, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 750073.25
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.

Going ahead to step 11:
250 divided by 27 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 750073.259
If we take 243 away from 250, we end up 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.

Moving on to step 12:
27 can be fit into 70 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 750073.2592
The remainder is 16 after subtracting 54 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
27 can be fit into 160 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 750073.25925
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
When dividing 250 by 27, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 750073.259259
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.

On to step 15:
The number 27 fits into 70 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 750073.2592592
The remainder is 16 after subtracting 54 from 70.
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 16:
The number 27 fits into 160 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 750073.25925925
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.

The final result is 750073.25925925 with a remainder of 2.5e-08.
