We're dividing 225623 by 11 
The aim is to understand the frequency of 11 in 225623.

On to step 1:
2 divided by 11 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 11

Going ahead to step 2:
11 can be fit into 22 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 22 from 22.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 11

Step 3:
11 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 5, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 11

Let's proceed to step 4:
56 divided by 11 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Subtract 55 from 56 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 11

Let's proceed to step 5:
If we divide 12 by 11, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 2051.0
Deduct 11 from 12 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 11

Let's proceed to step 6:
When dividing 13 by 11, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 20511.0
Deduct 11 from 13 and we're left 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.

On to step 7:
20 divided by 11 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 20511.1
The remainder is 9 after subtracting 11 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
The number 11 fits into 90 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 20511.18
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.

On 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: 20511.181
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.

On to step 10:
11 can be fit into 90 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 20511.1818
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 11:
11 goes into 20 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 20511.18181
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.
The next digit of our result is 8. 
Result so far: 20511.181818
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 13:
If we divide 20 by 11, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 20511.1818181
Subtract 11 from 20 to 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.

Step 14:
11 goes into 90 8 times with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 20511.18181818
If we subtract 88 from 90, we 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.

Our division results in 20511.18181818 with a remaining 2e-09.
