671837 ÷ 77 
The aim is to understand the frequency of 77 in 671837.

Let's proceed to step 1:
77 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 77

Going ahead to step 2:
When dividing 67 by 77, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 77

Advancing 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
The remainder is 55 after subtracting 616 from 671.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 77

Going ahead to step 4:
If we divide 558 by 77, we get 7 and a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 87.0
The remainder is 19 after subtracting 539 from 558.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 77

Going ahead to step 5:
The number 77 fits into 193 2 times, leaving a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 872.0
Subtract 154 from 193 to get 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 77

Going ahead to step 6:
The number 77 fits into 397 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 8725.0
If we subtract 385 from 397, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
77 can be fit into 120 1 times, resulting in a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 8725.1
Subtract 77 from 120 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 8:
430 divided by 77 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 8725.15
Subtracting 385 from 430 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
The number 77 fits into 450 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 8725.155
Subtracting 385 from 450 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 8725.155 with a balance of 0.0065.
