We're dividing 428013 by 11 
The aim is to understand the frequency of 11 in 428013.

Let's proceed to step 1:
The number 11 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 11

Moving on to step 2:
11 can be fit into 42 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 33 from 42 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 11

Let's proceed to step 3:
98 divided by 11 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 88 from 98 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 11

On to step 4:
11 can be fit into 100 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 389.0
If we subtract 99 from 100, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 11

Advancing to step 5:
11 can be fit into 11 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 3891.0
Subtracting 11 from 11 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 11

On to step 6:
When dividing 3 by 11, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 38910.0
If we take 0 away from 3, 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 7:
11 can be fit into 30 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 38910.2
Subtract 22 from 30 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
11 can be fit into 80 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 38910.27
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.

Moving on to step 9:
30 divided by 11 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 38910.272
The remainder is 8 after subtracting 22 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 11, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 38910.2727
Deduct 77 from 80 and we're left 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.

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: 38910.27272
If we subtract 22 from 30, we get 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:
11 goes into 80 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 38910.272727
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.

Going ahead to step 13:
When dividing 30 by 11, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 38910.2727272
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.

On to step 14:
When dividing 80 by 11, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 38910.27272727
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.

The final outcome is 38910.27272727, with a leftover of 3e-09.
