We look at the division of 716772 by 77 
The aim is to understand the frequency of 77 in 716772.

Advancing to step 1:
The number 77 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 77

Going ahead to step 2:
The number 77 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 77

Let's proceed to step 3:
When dividing 716 by 77, we get 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 693 from 716 and we're left with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 77

Advancing to step 4:
77 can be fit into 237 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 93.0
Deduct 231 from 237 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 77

Moving on to step 5:
When dividing 67 by 77, we get 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 930.0
The remainder is 67 after subtracting 0 from 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 77

Advancing to step 6:
The number 77 fits into 672 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 9308.0
If we take 616 away from 672, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
77 can be fit into 560 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 9308.7
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
77 can be fit into 210 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 9308.72
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
The number 77 fits into 560 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 9308.727
If we take 539 away from 560, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
If we divide 210 by 77, we get 2 and a remainder of 56.
The next digit of our result is 2. 
Result so far: 9308.7272
If we take 154 away from 210, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
When dividing 560 by 77, we get 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 9308.72727
Subtract 539 from 560 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
77 can be fit into 210 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 9308.727272
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
The number 77 fits into 560 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 9308.7272727
The remainder is 21 after subtracting 539 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
When dividing 210 by 77, we get 2 with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 9308.72727272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 9308.72727272 with a remaining 5.6e-08.
