Let's divide 288855 by 77
The aim is to understand the frequency of 77 in 288855.

Let's proceed to step 1:
If we divide 2 by 77, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 77

Step 2:
If we divide 28 by 77, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 77

Moving on to step 3:
If we divide 288 by 77, we get 3 and a remainder of 57.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 231 from 288 to get 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 77

Moving on to step 4:
77 can be fit into 578 7 times, resulting in a remainder of 39.
The next digit of our result is 7. 
Result so far: 37.0
The remainder is 39 after subtracting 539 from 578.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 77

Moving on to step 5:
When dividing 395 by 77, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
If we subtract 385 from 395, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 77

Moving on to step 6:
77 goes into 105 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 3751.0
If we take 77 away from 105, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
77 goes into 280 3 times with a remainder of 49.
The next digit of our result is 3. 
Result so far: 3751.3
Deduct 231 from 280 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
When dividing 490 by 77, we get 6 with a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 3751.36
The remainder is 28 after subtracting 462 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
If we divide 280 by 77, we get 3 and a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 3751.363
If we subtract 231 from 280, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 10:
77 goes into 490 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 3751.3636
If we subtract 462 from 490, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
The number 77 fits into 280 3 times, leaving a remainder of 49.
The next digit of our result is 3. 
Result so far: 3751.36363
Deduct 231 from 280 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
77 can be fit into 490 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 3751.363636
Deduct 462 from 490 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
77 can be fit into 280 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 3751.3636363
The remainder is 49 after subtracting 231 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 14:
When dividing 490 by 77, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 3751.36363636
If we take 462 away from 490, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 3751.36363636, with a leftover of 2.8e-08.
