454595 ÷ 77 
The aim is to understand the frequency of 77 in 454595.

On to step 1:
If we divide 4 by 77, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 77

Advancing to step 2:
77 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 77

Let's proceed to step 3:
77 can be fit into 454 5 times, resulting in a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 385 from 454 to get 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 77

On to step 4:
77 can be fit into 695 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 59.0
The remainder is 2 after subtracting 693 from 695.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 77

Step 5:
If we divide 29 by 77, we get 0 and a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 590.0
The remainder is 29 after subtracting 0 from 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 77

Let's proceed to step 6:
If we divide 295 by 77, we get 3 and a remainder of 64.
The next digit of our result is 3. 
Result so far: 5903.0
If we take 231 away from 295, we end up 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.

Advancing to step 7:
77 can be fit into 640 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 5903.8
Subtracting 616 from 640 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
77 can be fit into 240 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 5903.83
Subtract 231 from 240 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
77 can be fit into 90 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 5903.831
If we take 77 away from 90, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
When dividing 130 by 77, we get 1 with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 5903.8311
If we subtract 77 from 130, we 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.

The final result is 5903.8311 with a remainder of 0.00053.
