The aim is to understand the frequency of 27 in 77900299.

On to step 1:
7 divided by 27 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 27

On to step 2:
When dividing 77 by 27, we get 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 54 from 77 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 27

Moving on to step 3:
27 goes into 239 8 times with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 216 from 239 to get 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 27

On to step 4:
If we divide 230 by 27, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 288.0
If we subtract 216 from 230, we get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 27

Moving on to step 5:
When dividing 140 by 27, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2885.0
If we subtract 135 from 140, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 27

Moving on to step 6:
27 can be fit into 52 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 28851.0
Subtracting 27 from 52 leaves us with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 27

Let's proceed to step 7:
If we divide 259 by 27, we get 9 and a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 288519.0
Subtracting 243 from 259 leaves us with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 27

Let's proceed to step 8:
169 divided by 27 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 2885196.0
If we subtract 162 from 169, 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 9:
When dividing 70 by 27, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 2885196.2
Subtract 54 from 70 to 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.

Let's proceed to step 10:
When dividing 160 by 27, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 2885196.25
Subtracting 135 from 160 leaves us 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 11:
250 divided by 27 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2885196.259
Deduct 243 from 250 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.

Going ahead to step 12:
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: 2885196.2592
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.

Advancing to step 13:
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: 2885196.25925
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.

Moving on to step 14:
27 can be fit into 250 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2885196.259259
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.

Advancing to step 15:
When dividing 70 by 27, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2885196.2592592
Subtract 54 from 70 to 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.

Moving on to step 16:
When dividing 160 by 27, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 2885196.25925925
Subtract 135 from 160 to 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.

In conclusion, the division gives 2885196.25925925 with a balance of 2.5e-08.
