We look at the division of 30324079 by 77 
The aim is to understand the frequency of 77 in 30324079.

Let's proceed to step 1:
When dividing 3 by 77, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 77

Step 2:
When dividing 30 by 77, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 77

Moving on to step 3:
The number 77 fits into 303 3 times, leaving a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 72 after subtracting 231 from 303.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 77

Step 4:
The number 77 fits into 722 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 693 from 722 to get 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 77

Let's proceed to step 5:
77 goes into 294 3 times with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 393.0
Deduct 231 from 294 and we're left with 63.
Take the next digit (0) from the dividend and append it to 63, then repeat: 630 / 77

Moving on to step 6:
77 can be fit into 630 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 3938.0
Subtracting 616 from 630 leaves us with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 77

Going ahead to step 7:
If we divide 147 by 77, we get 1 and a remainder of 70.
The next digit of our result is 1. 
Result so far: 39381.0
Deduct 77 from 147 and we're left with 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 77

Advancing to step 8:
77 goes into 709 9 times with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 393819.0
Deduct 693 from 709 and we're left 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.

Going ahead to step 9:
160 divided by 77 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 393819.2
Deduct 154 from 160 and we're left 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.

Let's proceed to step 10:
77 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 393819.2
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 77 is 7 with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 393819.207
Deduct 539 from 600 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 12:
77 can be fit into 610 7 times, resulting in a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 393819.2077
If we take 539 away from 610, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 393819.2077 and a remainder of 0.00071.
