Let's divide 358565 by 77
The aim is to understand the frequency of 77 in 358565.

On to step 1:
If we divide 3 by 77, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 77

Let's proceed to step 2:
The number 77 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 77

Advancing to step 3:
77 goes into 358 4 times with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 308 from 358 to get 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 77

On to step 4:
77 goes into 505 6 times with a remainder of 43.
The next digit of our result is 6. 
Result so far: 46.0
Deduct 462 from 505 and we're left with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 77

Moving on to step 5:
If we divide 436 by 77, we get 5 and a remainder of 51.
Put 5 as the next digit of the answer. 
Result so far: 465.0
Deduct 385 from 436 and we're left with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 77

Step 6:
515 divided by 77 is 6 with a remainder of 53.
Record the quotient 6 as the next digit in the result. 
Result so far: 4656.0
Subtract 462 from 515 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
The number 77 fits into 530 6 times, leaving a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 4656.6
Deduct 462 from 530 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
680 divided by 77 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 4656.68
Deduct 616 from 680 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
77 goes into 640 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 4656.688
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 4656.688 with a remainder of 0.0024.
