Let's divide 648610 by 11
The aim is to understand the frequency of 11 in 648610.

On to step 1:
11 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 11

Advancing to step 2:
64 divided by 11 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 55 from 64 leaves us with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 11

Going ahead to step 3:
The number 11 fits into 98 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 58.0
The remainder is 10 after subtracting 88 from 98.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 11

Step 4:
If we divide 106 by 11, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 589.0
The remainder is 7 after subtracting 99 from 106.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 11

Going ahead to step 5:
When dividing 71 by 11, we get 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 5896.0
Subtracting 66 from 71 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 11

Moving on to step 6:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 58964.0
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.

Let's proceed to step 7:
11 goes into 60 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 58964.5
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.

On to step 8:
When dividing 50 by 11, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 58964.54
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.

Moving on to step 9:
If we divide 60 by 11, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 58964.545
Deduct 55 from 60 and we're left 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.

Step 10:
If we divide 50 by 11, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 58964.5454
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.

Let's proceed to step 11:
If we divide 60 by 11, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 58964.54545
Deduct 55 from 60 and we're left 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.

On to step 12:
When dividing 50 by 11, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 58964.545454
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.

Going ahead to step 13:
11 goes into 60 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 58964.5454545
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 14:
When dividing 50 by 11, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 58964.54545454
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.

The final outcome is 58964.54545454, with a leftover of 6e-09.
