We look at the division of 723404 by 11 
The aim is to understand the frequency of 11 in 723404.

On to step 1:
If we divide 7 by 11, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 11

Advancing to step 2:
72 divided by 11 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 66 from 72, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 11

Step 3:
11 goes into 63 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
If we subtract 55 from 63, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 11

On to step 4:
11 goes into 84 7 times with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 657.0
Deduct 77 from 84 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 11

Let's proceed to step 5:
If we divide 70 by 11, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6576.0
Subtract 66 from 70 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 11

Advancing to step 6:
If we divide 44 by 11, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 65764.0
Subtract 44 from 44 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 11, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 65764.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 11 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 65764.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 65764.0, with a leftover of 0.0.
