We divide 685600 by 77
The aim is to understand the frequency of 77 in 685600.

Going ahead to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 77

Advancing to step 2:
If we divide 68 by 77, we get 0 and a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 77

Moving on to step 3:
The number 77 fits into 685 8 times, leaving a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 616 away from 685, we end up with 69.
Fetch the next digit (6) from the dividend, attach it to 69 and continue: 696 / 77

Step 4:
When dividing 696 by 77, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtracting 693 from 696 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 77

Step 5:
When dividing 30 by 77, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 890.0
Subtracting 0 from 30 leaves us with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 77

Let's proceed to step 6:
77 goes into 300 3 times with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 8903.0
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
When dividing 690 by 77, we get 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 8903.8
The remainder is 74 after subtracting 616 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 8903.89
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 9:
When dividing 470 by 77, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 8903.896
If we take 462 away from 470, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 77 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 8903.8961
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
30 divided by 77 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8903.8961
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
300 divided by 77 is 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 8903.896103
The remainder is 69 after subtracting 231 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 13:
690 divided by 77 is 8 with a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 8903.8961038
If we take 616 away from 690, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 14:
77 can be fit into 740 9 times, resulting in a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 8903.89610389
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The quotient of the division is 8903.89610389, and the remainder is 4.7e-08.
