353728 divided by 77 
The aim is to understand the frequency of 77 in 353728.

Going ahead to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 77

Advancing to step 2:
77 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 77

Moving on to step 3:
77 goes into 353 4 times with a remainder of 45.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 308 from 353, we get 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 77

Advancing to step 4:
77 goes into 457 5 times with a remainder of 72.
Write down 5 as next digit of the result. 
Result so far: 45.0
The remainder is 72 after subtracting 385 from 457.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 77

Let's proceed to step 5:
77 can be fit into 722 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 459.0
Subtracting 693 from 722 leaves us with 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 77

Moving on to step 6:
298 divided by 77 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 4593.0
If we subtract 231 from 298, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
If we divide 670 by 77, we get 8 and a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 4593.8
Subtract 616 from 670 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
When dividing 540 by 77, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 4593.87
If we take 539 away from 540, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
10 divided by 77 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4593.87
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
100 divided by 77 is 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 4593.8701
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
If we divide 230 by 77, we get 2 and a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 4593.87012
Deduct 154 from 230 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
77 goes into 760 9 times with a remainder of 67.
The next digit of our result is 9. 
Result so far: 4593.870129
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
77 goes into 670 8 times with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 4593.8701298
If we take 616 away from 670, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
77 goes into 540 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 4593.87012987
Subtracting 539 from 540 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 4593.87012987 and a remainder of 1e-09.
