243366 ÷ 77 
The aim is to understand the frequency of 77 in 243366.

Advancing to step 1:
2 divided by 77 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 77

Moving on to step 2:
77 can be fit into 24 0 times, resulting in a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 77

On to step 3:
The number 77 fits into 243 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 231 away from 243, we end up with 12.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 77

Moving on to step 4:
When dividing 123 by 77, we get 1 with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 46 after subtracting 77 from 123.
Append the next digit (6) from the dividend to 46 and continue with: 466 / 77

Going ahead to step 5:
The number 77 fits into 466 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 316.0
Subtracting 462 from 466 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 77

Advancing to step 6:
When dividing 46 by 77, we get 0 with a remainder of 46.
The next digit of our result is 0. 
Result so far: 3160.0
Subtracting 0 from 46 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.

Step 7:
When dividing 460 by 77, we get 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3160.5
The remainder is 75 after subtracting 385 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 8:
750 divided by 77 is 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 3160.59
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.

Step 9:
77 goes into 570 7 times with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 3160.597
The remainder is 31 after subtracting 539 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
The number 77 fits into 310 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 3160.5974
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 77, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 3160.5974
Subtracting 0 from 20 leaves us 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.

Moving on to step 12:
77 can be fit into 200 2 times, resulting in a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 3160.597402
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 13:
460 divided by 77 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 3160.5974025
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.

Step 14:
77 goes into 750 9 times with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 3160.59740259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The quotient of the division is 3160.59740259, and the remainder is 5.7e-08.
