We're dividing 41252377 by 77 
The aim is to understand the frequency of 77 in 41252377.

Moving on to step 1:
When dividing 4 by 77, we get 0 with 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.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 77

Let's proceed to step 2:
If we divide 41 by 77, we get 0 and a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 77

Going ahead to step 3:
412 divided by 77 is 5 with a remainder of 27.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 27 after subtracting 385 from 412.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 77

Step 4:
If we divide 275 by 77, we get 3 and a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Deduct 231 from 275 and we're left with 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 77

Going ahead to step 5:
The number 77 fits into 442 5 times, leaving a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 535.0
Subtract 385 from 442 to get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 77

Let's proceed to step 6:
77 goes into 573 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 5357.0
Deduct 539 from 573 and we're left with 34.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 77

Let's proceed to step 7:
77 goes into 347 4 times with a remainder of 39.
The next digit of our result is 4. 
Result so far: 53574.0
If we take 308 away from 347, we end up with 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 77

Going ahead to step 8:
397 divided by 77 is 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 535745.0
Subtract 385 from 397 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
The number 77 fits into 120 1 times, leaving a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 535745.1
If we subtract 77 from 120, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
The number 77 fits into 430 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 535745.15
The remainder is 45 after subtracting 385 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
When dividing 450 by 77, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 535745.155
Subtract 385 from 450 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 535745.155, and the remainder is 0.0065.
