We're dividing 38379539 by 11 
The aim is to understand the frequency of 11 in 38379539.

Step 1:
The number 11 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 11

Advancing to step 2:
The number 11 fits into 38 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 33 from 38, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 11

Advancing to step 3:
The number 11 fits into 53 4 times, leaving a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 34.0
Subtract 44 from 53 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 11

On to step 4:
11 goes into 97 8 times with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 348.0
If we subtract 88 from 97, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 11

Going ahead to step 5:
11 can be fit into 99 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 3489.0
Subtracting 99 from 99 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 11

Advancing to step 6:
If we divide 5 by 11, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 34890.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 11

Step 7:
If we divide 53 by 11, we get 4 and a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 348904.0
If we subtract 44 from 53, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 11

Step 8:
When dividing 99 by 11, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 3489049.0
Subtract 99 from 99 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 9:
11 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3489049.0
Deduct 0 from 0 and we're left 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.

Advancing to step 10:
11 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3489049.0
Deduct 0 from 0 and we're left 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.

After the division, we end up with 3489049.0 and a remainder of 0.0.
