Let's divide 856488 by 77
The aim is to understand the frequency of 77 in 856488.

Advancing to step 1:
77 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 77

Let's proceed to step 2:
When dividing 85 by 77, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 77 from 85, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 77

Going ahead to step 3:
77 can be fit into 86 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 77 from 86, we get 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 77

Advancing to step 4:
When dividing 94 by 77, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
The remainder is 17 after subtracting 77 from 94.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 77

Advancing to step 5:
When dividing 178 by 77, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 1112.0
The remainder is 24 after subtracting 154 from 178.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 77

On to step 6:
248 divided by 77 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 11123.0
The remainder is 17 after subtracting 231 from 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
170 divided by 77 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 11123.2
Subtracting 154 from 170 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
When dividing 160 by 77, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 11123.22
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 11123.22 with a remainder of 0.006.
