585577 divided by 774 
The aim is to understand the frequency of 774 in 585577.

Advancing to step 1:
When dividing 5 by 774, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 774

On to step 2:
If we divide 58 by 774, we get 0 and a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 774

Moving on to step 3:
585 divided by 774 is 0 with a remainder of 585.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 585 and we're left with 585.
Append the next digit (5) from the dividend to 585 and continue with: 5855 / 774

Let's proceed to step 4:
When dividing 5855 by 774, we get 7 with a remainder of 437.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 5418 from 5855 leaves us with 437.
Take the next digit (7) from the dividend and append it to 437, then repeat: 4377 / 774

Going ahead to step 5:
When dividing 4377 by 774, we get 5 with a remainder of 507.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
If we subtract 3870 from 4377, we get 507.
Include the next digit (7) from the dividend after 507, then repeat: 5077 / 774

Moving on to step 6:
When dividing 5077 by 774, we get 6 with a remainder of 433.
Put 6 as the next digit of the answer. 
Result so far: 756.0
If we subtract 4644 from 5077, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Moving on to step 7:
774 can be fit into 4330 5 times, resulting in a remainder of 460.
The number 5 becomes the next digit in our result. 
Result so far: 756.5
Subtracting 3870 from 4330 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 8:
774 can be fit into 4600 5 times, resulting in a remainder of 730.
Put 5 as the next digit of the answer. 
Result so far: 756.55
Subtracting 3870 from 4600 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

The final outcome is 756.55, with a leftover of 0.73.
