We divide 8110503 by 11
The aim is to understand the frequency of 11 in 8110503.

On to step 1:
When dividing 8 by 11, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 11

Advancing to step 2:
The number 11 fits into 81 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 4 after subtracting 77 from 81.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 11

On to step 3:
When dividing 41 by 11, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we take 33 away from 41, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 11

Let's proceed to step 4:
80 divided by 11 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 737.0
If we subtract 77 from 80, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 11

Moving on to step 5:
11 can be fit into 35 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 7373.0
If we subtract 33 from 35, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 11

Going ahead to step 6:
The number 11 fits into 20 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 73731.0
The remainder is 9 after subtracting 11 from 20.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 11

Moving on to step 7:
11 can be fit into 93 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 737318.0
If we take 88 away from 93, we end up 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.

Moving on to step 8:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 737318.4
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.

Moving on to step 9:
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: 737318.45
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:
11 can be fit into 50 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 737318.454
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.

Let's proceed to step 11:
If we divide 60 by 11, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 737318.4545
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.

Moving on to step 12:
11 goes into 50 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 737318.45454
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.

Step 13:
The number 11 fits into 60 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 737318.454545
If we take 55 away from 60, we end up 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.

Going ahead to step 14:
11 goes into 50 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 737318.4545454
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.

Going ahead to step 15:
When dividing 60 by 11, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 737318.45454545
The remainder is 5 after subtracting 55 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 737318.45454545 and a remainder of 5e-09.
