We look at the division of 272292 by 77 
The aim is to understand the frequency of 77 in 272292.

Step 1:
When dividing 2 by 77, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 77

Advancing to step 2:
If we divide 27 by 77, we get 0 and a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Append the next digit (2) from the dividend to 27 and continue with: 272 / 77

Advancing to step 3:
77 can be fit into 272 3 times, resulting in a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 231 from 272 leaves us with 41.
Grab the next digit (2) from the dividend, add it to 41, then carry on: 412 / 77

Advancing to step 4:
When dividing 412 by 77, we get 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 385 away from 412, we end up with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 77

On to step 5:
If we divide 279 by 77, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 353.0
If we take 231 away from 279, we end up with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 77

On to step 6:
77 goes into 482 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3536.0
Subtract 462 from 482 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
When dividing 200 by 77, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 3536.2
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
77 goes into 460 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 3536.25
If we take 385 away from 460, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 3536.259
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
The number 77 fits into 570 7 times, leaving a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 3536.2597
Deduct 539 from 570 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 11:
310 divided by 77 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 3536.25974
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
77 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3536.25974
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 77, we get 2 and a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 3536.2597402
Deduct 154 from 200 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
460 divided by 77 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 3536.25974025
Subtracting 385 from 460 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Our division results in 3536.25974025 with a remaining 7.5e-08.
