Let's divide 671719 by 77
The aim is to understand the frequency of 77 in 671719.

Moving on to step 1:
The number 77 fits into 6 0 times, leaving 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.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 77

Moving on to step 2:
77 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 77

Let's proceed to step 3:
77 can be fit into 671 8 times, resulting in a remainder of 55.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 616 from 671 and we're left with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 77

Moving on to step 4:
557 divided by 77 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtract 539 from 557 to get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 77

Moving on to step 5:
If we divide 181 by 77, we get 2 and a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
The remainder is 27 after subtracting 154 from 181.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 77

Let's proceed to step 6:
77 can be fit into 279 3 times, resulting in a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 8723.0
The remainder is 48 after subtracting 231 from 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
When dividing 480 by 77, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 8723.6
Deduct 462 from 480 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
If we divide 180 by 77, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 8723.62
Subtracting 154 from 180 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
77 goes into 260 3 times with a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 8723.623
Deduct 231 from 260 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
290 divided by 77 is 3 with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 8723.6233
Subtract 231 from 290 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final result is 8723.6233 with a remainder of 0.00059.
