Let's divide 912881 by 77
The aim is to understand the frequency of 77 in 912881.

Step 1:
9 divided by 77 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 77

Step 2:
91 divided by 77 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 14 after subtracting 77 from 91.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 77

On to step 3:
77 goes into 142 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 77 from 142 leaves us with 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 77

Let's proceed to step 4:
658 divided by 77 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 118.0
Subtract 616 from 658 to get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 77

Going ahead to step 5:
77 goes into 428 5 times with a remainder of 43.
The next digit of our result is 5. 
Result so far: 1185.0
Deduct 385 from 428 and we're left with 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 77

Advancing to step 6:
When dividing 431 by 77, we get 5 with a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 11855.0
The remainder is 46 after subtracting 385 from 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
77 goes into 460 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 11855.5
If we subtract 385 from 460, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 8:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 11855.59
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
570 divided by 77 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 11855.597
If we subtract 539 from 570, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
77 goes into 310 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 11855.5974
If we take 308 away from 310, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
77 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 11855.5974
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
77 goes into 200 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 11855.597402
Subtracting 154 from 200 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
If we divide 460 by 77, we get 5 and a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 11855.5974025
Subtract 385 from 460 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
If we divide 750 by 77, we get 9 and a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 11855.59740259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The quotient of the division is 11855.59740259, and the remainder is 5.7e-08.
