438739 divided by 11 
The aim is to understand the frequency of 11 in 438739.

Let's proceed to step 1:
When dividing 4 by 11, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 11

On to step 2:
11 can be fit into 43 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 33 away from 43, we end up with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 11

Step 3:
108 divided by 11 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 99 from 108 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 11

Going ahead to step 4:
If we divide 97 by 11, we get 8 and a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 398.0
If we subtract 88 from 97, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 11

Let's proceed to step 5:
When dividing 93 by 11, we get 8 with a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 3988.0
Deduct 88 from 93 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 11

Let's proceed to step 6:
11 goes into 59 5 times with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 39885.0
Subtracting 55 from 59 leaves us 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.

Step 7:
If we divide 40 by 11, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 39885.3
Deduct 33 from 40 and we're left 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.

Let's proceed to step 8:
11 can be fit into 70 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 39885.36
Subtract 66 from 70 to 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 9:
When dividing 40 by 11, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 39885.363
Subtracting 33 from 40 leaves us 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 10:
11 goes into 70 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 39885.3636
Deduct 66 from 70 and we're left 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.

Going ahead to step 11:
The number 11 fits into 40 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 39885.36363
If we subtract 33 from 40, 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.

Advancing to step 12:
The number 11 fits into 70 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 39885.363636
Subtract 66 from 70 to 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.

On to step 13:
40 divided by 11 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 39885.3636363
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.

Let's proceed to step 14:
11 goes into 70 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 39885.36363636
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.

The final outcome is 39885.36363636, with a leftover of 4e-09.
