We divide 77861 by 11
The aim is to understand the frequency of 11 in 77861.

Moving on to step 1:
If we divide 7 by 11, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 11

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
Subtract 77 from 77 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 11

Step 3:
The number 11 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 70.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 11

Moving on to step 4:
11 goes into 86 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 707.0
Subtracting 77 from 86 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 11

Step 5:
11 goes into 91 8 times with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 7078.0
Deduct 88 from 91 and we're left 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.

Advancing to step 6:
When dividing 30 by 11, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 7078.2
If we subtract 22 from 30, we get 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 7:
80 divided by 11 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 7078.27
Subtract 77 from 80 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
30 divided by 11 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 7078.272
If we take 22 away from 30, 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.

On to step 9:
When dividing 80 by 11, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7078.2727
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
11 can be fit into 30 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 7078.27272
If we take 22 away from 30, 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.

Let's proceed to step 11:
If we divide 80 by 11, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 7078.272727
If we take 77 away from 80, we end up 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:
11 goes into 30 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 7078.2727272
Deduct 22 from 30 and we're left 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.

Going ahead to step 13:
The number 11 fits into 80 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 7078.27272727
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.

In conclusion, the division gives 7078.27272727 with a balance of 3e-09.
