We look at the division of 291949 by 77 
The aim is to understand the frequency of 77 in 291949.

Going ahead to step 1:
77 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 77

On to step 2:
When dividing 29 by 77, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 77

Moving on to step 3:
When dividing 291 by 77, we get 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 231 from 291 and we're left with 60.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 77

Moving on to step 4:
77 can be fit into 609 7 times, resulting in a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtract 539 from 609 to get 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 77

Let's proceed to step 5:
If we divide 704 by 77, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 379.0
The remainder is 11 after subtracting 693 from 704.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 77

Going ahead to step 6:
77 can be fit into 119 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 3791.0
Deduct 77 from 119 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
When dividing 420 by 77, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3791.5
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
77 can be fit into 350 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 3791.54
Subtracting 308 from 350 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
The number 77 fits into 420 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 3791.545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
350 divided by 77 is 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 3791.5454
The remainder is 42 after subtracting 308 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
77 goes into 420 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3791.54545
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 12:
When dividing 350 by 77, we get 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 3791.545454
If we subtract 308 from 350, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
420 divided by 77 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3791.5454545
If we take 385 away from 420, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
350 divided by 77 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 3791.54545454
Subtracting 308 from 350 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 3791.54545454 with a remaining 4.2e-08.
