155248 ÷ 11 
The aim is to understand the frequency of 11 in 155248.

Advancing to step 1:
When dividing 1 by 11, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 11

Let's proceed to step 2:
11 goes into 15 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 11 from 15 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 11

Step 3:
11 goes into 45 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 44 from 45 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 11

Going ahead to step 4:
12 divided by 11 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 141.0
The remainder is 1 after subtracting 11 from 12.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 11

Moving on to step 5:
When dividing 14 by 11, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1411.0
If we subtract 11 from 14, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 11

Advancing to step 6:
When dividing 38 by 11, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 14113.0
The remainder is 5 after subtracting 33 from 38.
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 7:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14113.4
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.

Step 8:
11 goes into 60 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 14113.45
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 9:
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: 14113.454
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.

Step 10:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 14113.4545
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.

Let's proceed to step 11:
The number 11 fits into 50 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14113.45454
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.

Moving on to step 12:
60 divided by 11 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 14113.454545
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.

Step 13:
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: 14113.4545454
Subtracting 44 from 50 leaves us 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 14:
When dividing 60 by 11, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 14113.45454545
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.

After the division, we end up with 14113.45454545 and a remainder of 5e-09.
