We divide 518603 by 11
The aim is to understand the frequency of 11 in 518603.

Let's proceed to step 1:
11 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 11

Moving on to step 2:
The number 11 fits into 51 4 times, leaving a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 44 from 51 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 11

Step 3:
The number 11 fits into 78 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 47.0
If we subtract 77 from 78, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 11

Going ahead to step 4:
11 goes into 16 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 471.0
The remainder is 5 after subtracting 11 from 16.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 11

Let's proceed to step 5:
When dividing 50 by 11, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4714.0
Deduct 44 from 50 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 11

Advancing to step 6:
If we divide 63 by 11, we get 5 and a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 47145.0
If we subtract 55 from 63, 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.

On to step 7:
When dividing 80 by 11, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 47145.7
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.

Step 8:
If we divide 30 by 11, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 47145.72
Subtract 22 from 30 to 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.

Let's proceed to step 9:
80 divided by 11 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 47145.727
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.

On to step 10:
30 divided by 11 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 47145.7272
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.

Moving on to step 11:
11 can be fit into 80 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 47145.72727
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.

Step 12:
When dividing 30 by 11, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 47145.727272
The remainder is 8 after subtracting 22 from 30.
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 13:
11 can be fit into 80 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 47145.7272727
Deduct 77 from 80 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.

Let's proceed to step 14:
11 can be fit into 30 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 47145.72727272
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.

The quotient of the division is 47145.72727272, and the remainder is 8e-09.
