886108 ÷ 77 
The aim is to understand the frequency of 77 in 886108.

On to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 77

Advancing to step 2:
77 goes into 88 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 77 from 88, we get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 77

On to step 3:
If we divide 116 by 77, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 77 from 116 leaves us with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 77

Moving on to step 4:
When dividing 391 by 77, we get 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 115.0
If we subtract 385 from 391, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 77

On to step 5:
If we divide 60 by 77, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 1150.0
If we take 0 away from 60, we end up with 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 77

Step 6:
If we divide 608 by 77, we get 7 and a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 11507.0
Subtracting 539 from 608 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
If we divide 690 by 77, we get 8 and a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 11507.8
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.

On to step 8:
740 divided by 77 is 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 11507.89
The remainder is 47 after subtracting 693 from 740.
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 9:
When dividing 470 by 77, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 11507.896
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.

Step 10:
80 divided by 77 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 11507.8961
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 11:
The number 77 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 11507.8961
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.

Going ahead to step 12:
The number 77 fits into 300 3 times, leaving a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 11507.896103
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 13:
When dividing 690 by 77, we get 8 with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 11507.8961038
If we subtract 616 from 690, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
77 can be fit into 740 9 times, resulting in a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 11507.89610389
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.

After the division, we end up with 11507.89610389 and a remainder of 4.7e-08.
