53496218 divided by 77 
The aim is to understand the frequency of 77 in 53496218.

Going ahead to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 77

On to step 2:
If we divide 53 by 77, we get 0 and a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Include the next digit (4) from the dividend after 53, then repeat: 534 / 77

Moving on to step 3:
When dividing 534 by 77, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 462 from 534 leaves us with 72.
Grab the next digit (9) from the dividend, add it to 72, then carry on: 729 / 77

Let's proceed to step 4:
729 divided by 77 is 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 69.0
Subtracting 693 from 729 leaves us with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 77

Going ahead to step 5:
If we divide 366 by 77, we get 4 and a remainder of 58.
The next digit of our result is 4. 
Result so far: 694.0
The remainder is 58 after subtracting 308 from 366.
Include the next digit (2) from the dividend after 58, then repeat: 582 / 77

Let's proceed to step 6:
77 goes into 582 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 6947.0
If we take 539 away from 582, we end up with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 77

On to step 7:
431 divided by 77 is 5 with a remainder of 46.
The next digit of our result is 5. 
Result so far: 69475.0
If we subtract 385 from 431, we get 46.
Take the next digit (8) from the dividend and append it to 46, then repeat: 468 / 77

Going ahead to step 8:
77 can be fit into 468 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 694756.0
If we take 462 away from 468, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 77, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 694756.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
If we divide 600 by 77, we get 7 and a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 694756.07
If we subtract 539 from 600, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
77 can be fit into 610 7 times, resulting in a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 694756.077
Subtracting 539 from 610 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final result is 694756.077 with a remainder of 0.0071.
