Let's divide 900507 by 11
The aim is to understand the frequency of 11 in 900507.

Going ahead to step 1:
11 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 11

On to step 2:
11 goes into 90 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 88 from 90 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 11

Let's proceed to step 3:
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: 81.0
Subtract 11 from 20 to get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 11

Advancing to step 4:
The number 11 fits into 95 8 times, leaving a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 818.0
Deduct 88 from 95 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 11

Step 5:
The number 11 fits into 70 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 8186.0
Subtract 66 from 70 to get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 11

Moving on to step 6:
11 can be fit into 47 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 81864.0
Subtract 44 from 47 to get 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 7:
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: 81864.2
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 8:
11 goes into 80 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 81864.27
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.

Let's proceed to step 9:
The number 11 fits into 30 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 81864.272
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 10:
11 can be fit into 80 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 81864.2727
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.

On to step 11:
11 goes into 30 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 81864.27272
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.

Moving on to step 12:
If we divide 80 by 11, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 81864.272727
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.

Going ahead to step 13:
11 can be fit into 30 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 81864.2727272
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.

Moving on to step 14:
80 divided by 11 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 81864.27272727
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.

After the division, we end up with 81864.27272727 and a remainder of 3e-09.
