We're dividing 777998 by 11 
The aim is to understand the frequency of 11 in 777998.

On to step 1:
When dividing 7 by 11, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 11

Step 2:
77 divided by 11 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 77 from 77 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 11

Moving on to step 3:
11 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 11

Advancing to step 4:
11 can be fit into 79 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 707.0
Subtract 77 from 79 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 11

Advancing to step 5:
The number 11 fits into 29 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 7072.0
Subtracting 22 from 29 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 11

Step 6:
78 divided by 11 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 70727.0
Subtracting 77 from 78 leaves us 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.

Let's proceed to step 7:
The number 11 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 70727.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 11, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 70727.09
Subtracting 99 from 100 leaves us 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.

Advancing to step 9:
If we divide 10 by 11, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 70727.09
Subtracting 0 from 10 leaves us with 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 10:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 70727.0909
If we subtract 99 from 100, 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.

Going ahead to step 11:
10 divided by 11 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 70727.0909
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.

Let's proceed to step 12:
When dividing 100 by 11, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 70727.090909
If we subtract 99 from 100, 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.

Let's proceed to step 13:
When dividing 10 by 11, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 70727.090909
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 70727.09090909
Subtracting 99 from 100 leaves us 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.

The final outcome is 70727.09090909, with a leftover of 1e-09.
