777904 ÷ 11 
The aim is to understand the frequency of 11 in 777904.

Going ahead to step 1:
If we divide 7 by 11, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 11

Advancing to step 2:
11 can be fit into 77 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 77 from 77, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 11

Advancing to step 3:
11 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 11

Going ahead to step 4:
11 goes into 79 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 707.0
Subtracting 77 from 79 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 11

Step 5:
When dividing 20 by 11, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 7071.0
Deduct 11 from 20 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 11

Step 6:
When dividing 94 by 11, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 70718.0
Subtract 88 from 94 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 70718.5
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
11 goes into 50 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 70718.54
If we subtract 44 from 50, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
11 goes into 60 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 70718.545
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 10:
50 divided by 11 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 70718.5454
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 70718.54545
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
11 can be fit into 50 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 70718.545454
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 70718.5454545
If we subtract 55 from 60, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
If we divide 50 by 11, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 70718.54545454
If we take 44 away from 50, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 70718.54545454 and a remainder of 6e-09.
