We're dividing 127751 by 77 
The aim is to understand the frequency of 77 in 127751.

On to step 1:
1 divided by 77 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 77

Let's proceed to step 2:
77 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 77

On to step 3:
77 goes into 127 1 times with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 77 from 127, we get 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 77

Going ahead to step 4:
77 goes into 507 6 times with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 45 after subtracting 462 from 507.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 77

Step 5:
The number 77 fits into 455 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 165.0
The remainder is 70 after subtracting 385 from 455.
Take the next digit (1) from the dividend and append it to 70, then repeat: 701 / 77

Advancing to step 6:
If we divide 701 by 77, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 1659.0
The remainder is 8 after subtracting 693 from 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
77 goes into 80 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1659.1
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
When dividing 30 by 77, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1659.1
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
77 can be fit into 300 3 times, resulting in a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 1659.103
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
If we divide 690 by 77, we get 8 and a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 1659.1038
Subtracting 616 from 690 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
When dividing 740 by 77, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 1659.10389
Subtract 693 from 740 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
470 divided by 77 is 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 1659.103896
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
80 divided by 77 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1659.1038961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
When dividing 30 by 77, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 1659.1038961
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 1659.1038961, and the remainder is 3e-08.
