50495723 ÷ 11 
The aim is to understand the frequency of 11 in 50495723.

Let's proceed to step 1:
If we divide 5 by 11, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 11

Step 2:
When dividing 50 by 11, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 44 from 50 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 11

On to step 3:
11 goes into 64 5 times with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 9 after subtracting 55 from 64.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 11

Moving on to step 4:
99 divided by 11 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 459.0
Subtracting 99 from 99 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 11

On to step 5:
If we divide 5 by 11, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 4590.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 11

Advancing to step 6:
When dividing 57 by 11, we get 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 45905.0
If we take 55 away from 57, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 11

Advancing to step 7:
22 divided by 11 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 459052.0
Subtracting 22 from 22 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 11

Let's proceed to step 8:
3 divided by 11 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 4590520.0
If we subtract 0 from 3, we 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 9:
When dividing 30 by 11, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 4590520.2
Subtracting 22 from 30 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 11, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4590520.27
If we take 77 away from 80, we end up 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 11:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4590520.272
Deduct 22 from 30 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 11, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 4590520.2727
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.

Moving on to step 13:
When dividing 30 by 11, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 4590520.27272
Subtracting 22 from 30 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
If we divide 80 by 11, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 4590520.272727
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 15:
11 goes into 30 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4590520.2727272
Subtracting 22 from 30 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 16:
If we divide 80 by 11, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 4590520.27272727
If we subtract 77 from 80, we 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.

The quotient of the division is 4590520.27272727, and the remainder is 3e-09.
