We look at the division of 583995 by 77 
The aim is to understand the frequency of 77 in 583995.

Going ahead to step 1:
5 divided by 77 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 77

On to step 2:
When dividing 58 by 77, we get 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 77

On to step 3:
77 goes into 583 7 times with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 539 from 583 leaves us with 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 77

Moving on to step 4:
When dividing 449 by 77, we get 5 with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 64 after subtracting 385 from 449.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 77

Going ahead to step 5:
77 can be fit into 649 8 times, resulting in a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 758.0
If we subtract 616 from 649, we get 33.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 77

Moving on to step 6:
The number 77 fits into 335 4 times, leaving a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 7584.0
The remainder is 27 after subtracting 308 from 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
The number 77 fits into 270 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 7584.3
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 8:
77 goes into 390 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 7584.35
If we subtract 385 from 390, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 77, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 7584.35
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
77 can be fit into 500 6 times, resulting in a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 7584.3506
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
77 can be fit into 380 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 7584.35064
If we subtract 308 from 380, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
If we divide 720 by 77, we get 9 and a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 7584.350649
Subtract 693 from 720 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
77 goes into 270 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 7584.3506493
If we subtract 231 from 270, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 14:
The number 77 fits into 390 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7584.35064935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 7584.35064935 with a remaining 5e-09.
