We divide 528838 by 11
The aim is to understand the frequency of 11 in 528838.

Step 1:
If we divide 5 by 11, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 11

Going ahead to step 2:
52 divided by 11 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 44 from 52, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 11

On to step 3:
If we divide 88 by 11, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 88 from 88 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 11

Going ahead to step 4:
When dividing 8 by 11, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 480.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 11

Moving on to step 5:
83 divided by 11 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 4807.0
The remainder is 6 after subtracting 77 from 83.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 11

Advancing to step 6:
The number 11 fits into 68 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 48076.0
Subtract 66 from 68 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
11 can be fit into 20 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 48076.1
Deduct 11 from 20 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 48076.18
Subtract 88 from 90 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
11 can be fit into 20 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 48076.181
If we subtract 11 from 20, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
When dividing 90 by 11, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 48076.1818
If we take 88 away from 90, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
20 divided by 11 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 48076.18181
If we take 11 away from 20, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
90 divided by 11 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 48076.181818
The remainder is 2 after subtracting 88 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 11, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 48076.1818181
Subtracting 11 from 20 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
11 goes into 90 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 48076.18181818
Subtracting 88 from 90 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 48076.18181818 with a remaining 2e-09.
