623529 ÷ 11 
The aim is to understand the frequency of 11 in 623529.

Step 1:
When dividing 6 by 11, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 11

Moving on to step 2:
62 divided by 11 is 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 55 from 62 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 11

On to step 3:
When dividing 73 by 11, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Deduct 66 from 73 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 11

Let's proceed to step 4:
11 goes into 75 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 566.0
Deduct 66 from 75 and we're left with 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 11

Advancing to step 5:
92 divided by 11 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 5668.0
Subtracting 88 from 92 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 11

Let's proceed to step 6:
11 goes into 49 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 56684.0
The remainder is 5 after subtracting 44 from 49.
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 7:
The number 11 fits into 50 4 times, leaving a remainder of 6.
The next digit of our result is 4. 
Result so far: 56684.4
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 8:
If we divide 60 by 11, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 56684.45
Subtract 55 from 60 to get 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 9:
11 can be fit into 50 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 56684.454
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.

Step 10:
60 divided by 11 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 56684.4545
Subtract 55 from 60 to get 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 11:
The number 11 fits into 50 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 56684.45454
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.

Moving on to step 12:
11 can be fit into 60 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 56684.454545
Subtract 55 from 60 to get 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 13:
When dividing 50 by 11, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 56684.4545454
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.

Moving on to step 14:
11 goes into 60 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 56684.45454545
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.

The quotient of the division is 56684.45454545, and the remainder is 5e-09.
