77945596 divided by 455 
The aim is to understand the frequency of 455 in 77945596.

Let's proceed to step 1:
When dividing 7 by 455, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 455

Moving on to step 2:
455 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 455

Going ahead to step 3:
If we divide 779 by 455, we get 1 and a remainder of 324.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 324 after subtracting 455 from 779.
Append the next digit (4) from the dividend to 324 and continue with: 3244 / 455

Going ahead to step 4:
If we divide 3244 by 455, we get 7 and a remainder of 59.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 3185 from 3244 leaves us with 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 455

Step 5:
595 divided by 455 is 1 with a remainder of 140.
The next digit of our result is 1. 
Result so far: 171.0
Subtracting 455 from 595 leaves us with 140.
Bring next digit (5) of the dividend behind the 140 and repeat the process: 1405 / 455

On to step 6:
If we divide 1405 by 455, we get 3 and a remainder of 40.
The next digit of our result is 3. 
Result so far: 1713.0
If we subtract 1365 from 1405, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 455

Advancing to step 7:
455 can be fit into 409 0 times, resulting in a remainder of 409.
The next digit of our result is 0. 
Result so far: 17130.0
Deduct 0 from 409 and we're left with 409.
Grab the next digit (6) from the dividend, add it to 409, then carry on: 4096 / 455

Step 8:
When dividing 4096 by 455, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 171309.0
If we subtract 4095 from 4096, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
The number 455 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 171309.0
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 455 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 171309.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 171309.0 and a remainder of 0.1.
