450242 divided by 77 
The aim is to understand the frequency of 77 in 450242.

Going ahead to step 1:
If we divide 4 by 77, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 77

On to step 2:
When dividing 45 by 77, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 77

Moving on to step 3:
If we divide 450 by 77, we get 5 and a remainder of 65.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 65 after subtracting 385 from 450.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 77

Going ahead to step 4:
652 divided by 77 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 58.0
Subtract 616 from 652 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 77

On to step 5:
If we divide 364 by 77, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 584.0
Subtracting 308 from 364 leaves us with 56.
Include the next digit (2) from the dividend after 56, then repeat: 562 / 77

On to step 6:
77 can be fit into 562 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 5847.0
The remainder is 23 after subtracting 539 from 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
230 divided by 77 is 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 5847.2
If we subtract 154 from 230, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 8:
If we divide 760 by 77, we get 9 and a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 5847.29
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
670 divided by 77 is 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 5847.298
Subtracting 616 from 670 leaves us 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 10:
77 can be fit into 540 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 5847.2987
If we subtract 539 from 540, 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.

On to step 11:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 5847.2987
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 77 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 5847.298701
If we subtract 77 from 100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
When dividing 230 by 77, we get 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 5847.2987012
If we take 154 away from 230, we end up 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 14:
760 divided by 77 is 9 with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 5847.29870129
Subtract 693 from 760 to 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.

After the division, we end up with 5847.29870129 and a remainder of 6.7e-08.
