Let's divide 815796 by 77
The aim is to understand the frequency of 77 in 815796.

Let's proceed to step 1:
77 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 77

Moving on to step 2:
The number 77 fits into 81 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 77 from 81 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 77

Moving on to step 3:
If we divide 45 by 77, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 77

Step 4:
77 goes into 457 5 times with a remainder of 72.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we subtract 385 from 457, we get 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 77

On to step 5:
When dividing 729 by 77, we get 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 1059.0
Subtract 693 from 729 to get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 77

Let's proceed to step 6:
77 can be fit into 366 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 10594.0
Subtracting 308 from 366 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 7:
The number 77 fits into 580 7 times, leaving a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 10594.7
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.

On to step 8:
77 goes into 410 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 10594.75
Deduct 385 from 410 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
250 divided by 77 is 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 10594.753
Subtracting 231 from 250 leaves us 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.

Moving on to step 10:
If we divide 190 by 77, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 10594.7532
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.

On to step 11:
77 can be fit into 360 4 times, resulting in a remainder of 52.
The next digit of our result is 4. 
Result so far: 10594.75324
If we take 308 away from 360, we end up 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.

Advancing to step 12:
520 divided by 77 is 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 10594.753246
Subtracting 462 from 520 leaves us with 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 13:
When dividing 580 by 77, we get 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 10594.7532467
The remainder is 41 after subtracting 539 from 580.
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 14:
The number 77 fits into 410 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 10594.75324675
If we subtract 385 from 410, we 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.

Our division results in 10594.75324675 with a remaining 2.5e-08.
