We look at the division of 96281571 by 77 
The aim is to understand the frequency of 77 in 96281571.

Advancing to step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 77

Let's proceed to step 2:
The number 77 fits into 96 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 77 from 96 and we're left with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 77

Going ahead to step 3:
77 goes into 192 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 154 from 192 leaves us with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 77

Moving on to step 4:
The number 77 fits into 388 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
The remainder is 3 after subtracting 385 from 388.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 77

Step 5:
The number 77 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 1250.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 77

Going ahead to step 6:
If we divide 315 by 77, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 12504.0
If we subtract 308 from 315, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 77

Step 7:
The number 77 fits into 77 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 125041.0
If we take 77 away from 77, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 77

Let's proceed to step 8:
When dividing 1 by 77, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 1250410.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
If we divide 10 by 77, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1250410.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
77 can be fit into 100 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1250410.01
Deduct 77 from 100 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
230 divided by 77 is 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 1250410.012
If we subtract 154 from 230, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
The number 77 fits into 760 9 times, leaving a remainder of 67.
The next digit of our result is 9. 
Result so far: 1250410.0129
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
The number 77 fits into 670 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 1250410.01298
If we subtract 616 from 670, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
When dividing 540 by 77, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1250410.012987
If we subtract 539 from 540, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 15:
The number 77 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1250410.012987
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
If we divide 100 by 77, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1250410.01298701
Subtract 77 from 100 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 1250410.01298701 with a remainder of 2.3e-08.
