We divide 258617 by 11
The aim is to understand the frequency of 11 in 258617.

Going ahead to step 1:
If we divide 2 by 11, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 11

Going ahead to step 2:
11 can be fit into 25 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 22 away from 25, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 11

On to step 3:
The number 11 fits into 38 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 33 from 38, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 11

Moving on to step 4:
11 goes into 56 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 235.0
If we take 55 away from 56, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 11

Advancing to step 5:
11 divided by 11 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 2351.0
The remainder is 0 after subtracting 11 from 11.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 11

Going ahead to step 6:
The number 11 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 23510.0
If we subtract 0 from 7, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 11, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 23510.6
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 11, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 23510.63
The remainder is 7 after subtracting 33 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
70 divided by 11 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 23510.636
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 23510.6363
If we take 33 away from 40, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
70 divided by 11 is 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 23510.63636
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 11 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 23510.636363
Subtract 33 from 40 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
11 goes into 70 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 23510.6363636
If we subtract 66 from 70, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
If we divide 40 by 11, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 23510.63636363
The remainder is 7 after subtracting 33 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 23510.63636363, with a leftover of 7e-09.
