We look at the division of 80011617 by 771 
The aim is to understand the frequency of 771 in 80011617.

Advancing to step 1:
When dividing 8 by 771, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 771

Moving on to step 2:
The number 771 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (0) from the dividend, add it to 80, then carry on: 800 / 771

Moving on to step 3:
800 divided by 771 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 771 from 800 leaves us with 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 771

On to step 4:
771 goes into 291 0 times with a remainder of 291.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 291, we end up with 291.
Grab the next digit (1) from the dividend, add it to 291, then carry on: 2911 / 771

On to step 5:
When dividing 2911 by 771, we get 3 with a remainder of 598.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we subtract 2313 from 2911, we get 598.
Append the next digit (6) from the dividend to 598 and continue with: 5986 / 771

On to step 6:
The number 771 fits into 5986 7 times, leaving a remainder of 589.
The next digit of our result is 7. 
Result so far: 1037.0
If we take 5397 away from 5986, we end up with 589.
Append the next digit (1) from the dividend to 589 and continue with: 5891 / 771

Advancing to step 7:
771 can be fit into 5891 7 times, resulting in a remainder of 494.
The number 7 becomes the next digit in our result. 
Result so far: 10377.0
Subtracting 5397 from 5891 leaves us with 494.
Grab the next digit (7) from the dividend, add it to 494, then carry on: 4947 / 771

On to step 8:
771 can be fit into 4947 6 times, resulting in a remainder of 321.
Use 6 as the next digit of our solution. 
Result so far: 103776.0
The remainder is 321 after subtracting 4626 from 4947.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Moving on to step 9:
The number 771 fits into 3210 4 times, leaving a remainder of 126.
Record the quotient 4 as the next digit in the result. 
Result so far: 103776.4
If we take 3084 away from 3210, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 10:
When dividing 1260 by 771, we get 1 with a remainder of 489.
The number 1 becomes the next digit in our result. 
Result so far: 103776.41
The remainder is 489 after subtracting 771 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Step 11:
The number 771 fits into 4890 6 times, leaving a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 103776.416
If we take 4626 away from 4890, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 12:
771 can be fit into 2640 3 times, resulting in a remainder of 327.
The next digit of our result is 3. 
Result so far: 103776.4163
Deduct 2313 from 2640 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 13:
771 goes into 3270 4 times with a remainder of 186.
Put 4 as the next digit of the answer. 
Result so far: 103776.41634
Deduct 3084 from 3270 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 14:
When dividing 1860 by 771, we get 2 with a remainder of 318.
The next digit of our result is 2. 
Result so far: 103776.416342
If we subtract 1542 from 1860, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 15:
When dividing 3180 by 771, we get 4 with a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 103776.4163424
If we subtract 3084 from 3180, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 16:
771 goes into 960 1 times with a remainder of 189.
The number 1 becomes the next digit in our result. 
Result so far: 103776.41634241
Subtract 771 from 960 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

In conclusion, the division gives 103776.41634241 with a balance of 1.89e-07.
