We look at the division of 655460 by 77 
The aim is to understand the frequency of 77 in 655460.

Step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 77

Let's proceed to step 2:
77 can be fit into 65 0 times, resulting in a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 77

Going ahead to step 3:
655 divided by 77 is 8 with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 616 from 655 and we're left with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 77

Going ahead to step 4:
394 divided by 77 is 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtracting 385 from 394 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 77

Advancing to step 5:
77 can be fit into 96 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 851.0
The remainder is 19 after subtracting 77 from 96.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 77

Going ahead to step 6:
If we divide 190 by 77, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 8512.0
The remainder is 36 after subtracting 154 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 77 fits into 360 4 times, leaving a remainder of 52.
The next digit of our result is 4. 
Result so far: 8512.4
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 8:
When dividing 520 by 77, we get 6 with a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 8512.46
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
If we divide 580 by 77, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 8512.467
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.

Step 10:
The number 77 fits into 410 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 8512.4675
The remainder is 25 after subtracting 385 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
77 can be fit into 250 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 8512.46753
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.

Let's proceed to step 12:
If we divide 190 by 77, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 8512.467532
If we take 154 away from 190, we end up 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.

Let's proceed to step 13:
77 can be fit into 360 4 times, resulting in a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 8512.4675324
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.

Advancing to step 14:
520 divided by 77 is 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 8512.46753246
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.

The final result is 8512.46753246 with a remainder of 5.8e-08.
