We divide 13443537 by 11
The aim is to understand the frequency of 11 in 13443537.

On to step 1:
If we divide 1 by 11, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 11

Moving on to step 2:
11 goes into 13 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 11 from 13 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 11

Step 3:
11 can be fit into 24 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 2 after subtracting 22 from 24.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 11

Going ahead to step 4:
11 can be fit into 24 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 122.0
Deduct 22 from 24 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 11

On to step 5:
When dividing 23 by 11, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 1222.0
Deduct 22 from 23 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 11

Let's proceed to step 6:
11 goes into 15 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 12221.0
Subtracting 11 from 15 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 11

Advancing to step 7:
11 goes into 43 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 122213.0
If we take 33 away from 43, we end up with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 11

Advancing to step 8:
107 divided by 11 is 9 with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 1222139.0
If we take 99 away from 107, we end up 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.

Going ahead to step 9:
11 goes into 80 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1222139.7
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.

On to step 10:
When dividing 30 by 11, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 1222139.72
If we take 22 away from 30, we end up 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 11:
The number 11 fits into 80 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 1222139.727
Subtracting 77 from 80 leaves us 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.

Advancing to step 12:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1222139.7272
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 13:
11 can be fit into 80 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1222139.72727
Subtracting 77 from 80 leaves us 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 14:
If we divide 30 by 11, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 1222139.727272
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.

Let's proceed to step 15:
11 can be fit into 80 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 1222139.7272727
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.

Step 16:
When dividing 30 by 11, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 1222139.72727272
Subtracting 22 from 30 leaves us 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.

Our division results in 1222139.72727272 with a remaining 8e-09.
