Let's divide 880756 by 77
The aim is to understand the frequency of 77 in 880756.

Step 1:
77 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 77

Moving on to step 2:
If we divide 88 by 77, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 11 after subtracting 77 from 88.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 77

Advancing to step 3:
77 goes into 110 1 times with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 77 from 110 to get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 77

Moving on to step 4:
When dividing 337 by 77, we get 4 with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Subtracting 308 from 337 leaves us with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 77

Step 5:
The number 77 fits into 295 3 times, leaving a remainder of 64.
Put 3 as the next digit of the answer. 
Result so far: 1143.0
Subtracting 231 from 295 leaves us with 64.
Take the next digit (6) from the dividend and append it to 64, then repeat: 646 / 77

Let's proceed to step 6:
77 goes into 646 8 times with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 11438.0
Subtract 616 from 646 to 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.

Moving on to step 7:
300 divided by 77 is 3 with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 11438.3
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 8:
The number 77 fits into 690 8 times, leaving a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 11438.38
If we take 616 away from 690, we end up 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.

Going ahead to step 9:
77 goes into 740 9 times with a remainder of 47.
The next digit of our result is 9. 
Result so far: 11438.389
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
The number 77 fits into 470 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 11438.3896
If we take 462 away from 470, we end up 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.

Advancing to step 11:
The number 77 fits into 80 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 11438.38961
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 12:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 11438.38961
Subtract 0 from 30 to 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 13:
77 can be fit into 300 3 times, resulting in a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 11438.3896103
If we subtract 231 from 300, we 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.

Let's proceed to step 14:
77 can be fit into 690 8 times, resulting in a remainder of 74.
The next digit of our result is 8. 
Result so far: 11438.38961038
Deduct 616 from 690 and we're left 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.

The final result is 11438.38961038 with a remainder of 7.4e-08.
