285766 ÷ 77 
The aim is to understand the frequency of 77 in 285766.

Going ahead to step 1:
The number 77 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 77

Moving on to step 2:
When dividing 28 by 77, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 77

Step 3:
The number 77 fits into 285 3 times, leaving a remainder of 54.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 231 away from 285, we end up with 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 77

Advancing to step 4:
The number 77 fits into 547 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 37.0
If we take 539 away from 547, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 77

Let's proceed to step 5:
If we divide 86 by 77, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 371.0
If we subtract 77 from 86, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 77

Advancing to step 6:
When dividing 96 by 77, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 3711.0
Deduct 77 from 96 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
77 can be fit into 190 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 3711.2
Subtracting 154 from 190 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
If we divide 360 by 77, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 3711.24
Subtracting 308 from 360 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
77 can be fit into 520 6 times, resulting in a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 3711.246
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
580 divided by 77 is 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 3711.2467
Subtract 539 from 580 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 11:
When dividing 410 by 77, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 3711.24675
Subtract 385 from 410 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.

Advancing to step 12:
When dividing 250 by 77, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 3711.246753
Deduct 231 from 250 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
The number 77 fits into 190 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3711.2467532
If we subtract 154 from 190, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
When dividing 360 by 77, we get 4 with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 3711.24675324
The remainder is 52 after subtracting 308 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 3711.24675324 with a balance of 5.2e-08.
