We look at the division of 82121606 by 911 
The aim is to understand the frequency of 911 in 82121606.

Step 1:
When dividing 8 by 911, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 911

Going ahead to step 2:
82 divided by 911 is 0 with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Grab the next digit (1) from the dividend, add it to 82, then carry on: 821 / 911

Going ahead to step 3:
If we divide 821 by 911, we get 0 and a remainder of 821.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 821 leaves us with 821.
Fetch the next digit (2) from the dividend, attach it to 821 and continue: 8212 / 911

Going ahead to step 4:
If we divide 8212 by 911, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 9.0
If we take 8199 away from 8212, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 911

Step 5:
The number 911 fits into 131 0 times, leaving a remainder of 131.
Write down 0 as next digit of the result. 
Result so far: 90.0
Subtracting 0 from 131 leaves us with 131.
Include the next digit (6) from the dividend after 131, then repeat: 1316 / 911

Let's proceed to step 6:
If we divide 1316 by 911, we get 1 and a remainder of 405.
Write down 1 as next digit of the result. 
Result so far: 901.0
If we take 911 away from 1316, we end up with 405.
Append the next digit (0) from the dividend to 405 and continue with: 4050 / 911

On to step 7:
If we divide 4050 by 911, we get 4 and a remainder of 406.
The number 4 becomes the next digit in our result. 
Result so far: 9014.0
If we take 3644 away from 4050, we end up with 406.
Bring next digit (6) of the dividend behind the 406 and repeat the process: 4066 / 911

Let's proceed to step 8:
If we divide 4066 by 911, we get 4 and a remainder of 422.
The number 4 becomes the next digit in our result. 
Result so far: 90144.0
If we subtract 3644 from 4066, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 9:
When dividing 4220 by 911, we get 4 with a remainder of 576.
Write down 4 as next digit of the result. 
Result so far: 90144.4
Subtracting 3644 from 4220 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 10:
5760 divided by 911 is 6 with a remainder of 294.
The number 6 becomes the next digit in our result. 
Result so far: 90144.46
Deduct 5466 from 5760 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 11:
2940 divided by 911 is 3 with a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 90144.463
Deduct 2733 from 2940 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 12:
If we divide 2070 by 911, we get 2 and a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 90144.4632
Subtracting 1822 from 2070 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 13:
The number 911 fits into 2480 2 times, leaving a remainder of 658.
Write down 2 as next digit of the result. 
Result so far: 90144.46322
The remainder is 658 after subtracting 1822 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

After the division, we end up with 90144.46322 and a remainder of 0.000658.
