We're dividing 71660026 by 911 
The aim is to understand the frequency of 911 in 71660026.

On to step 1:
The number 911 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 911

Let's proceed to step 2:
The number 911 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 911

Going ahead to step 3:
911 goes into 716 0 times with a remainder of 716.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 716 after subtracting 0 from 716.
Fetch the next digit (6) from the dividend, attach it to 716 and continue: 7166 / 911

Step 4:
When dividing 7166 by 911, we get 7 with a remainder of 789.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6377 from 7166 to get 789.
Take the next digit (0) from the dividend and append it to 789, then repeat: 7890 / 911

Advancing to step 5:
911 can be fit into 7890 8 times, resulting in a remainder of 602.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 7288 from 7890 and we're left with 602.
Fetch the next digit (0) from the dividend, attach it to 602 and continue: 6020 / 911

Let's proceed to step 6:
If we divide 6020 by 911, we get 6 and a remainder of 554.
Record the quotient 6 as the next digit in the result. 
Result so far: 786.0
If we subtract 5466 from 6020, we get 554.
Include the next digit (2) from the dividend after 554, then repeat: 5542 / 911

Going ahead to step 7:
5542 divided by 911 is 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 7866.0
Deduct 5466 from 5542 and we're left with 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 911

Let's proceed to step 8:
The number 911 fits into 766 0 times, leaving a remainder of 766.
The number 0 becomes the next digit in our result. 
Result so far: 78660.0
If we take 0 away from 766, we end up with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Step 9:
The number 911 fits into 7660 8 times, leaving a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 78660.8
Subtracting 7288 from 7660 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 10:
911 goes into 3720 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 78660.84
Deduct 3644 from 3720 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
911 can be fit into 760 0 times, resulting in a remainder of 760.
The number 0 becomes the next digit in our result. 
Result so far: 78660.84
The remainder is 760 after subtracting 0 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 12:
911 can be fit into 7600 8 times, resulting in a remainder of 312.
The next digit of our result is 8. 
Result so far: 78660.8408
If we take 7288 away from 7600, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 13:
If we divide 3120 by 911, we get 3 and a remainder of 387.
Record the quotient 3 as the next digit in the result. 
Result so far: 78660.84083
If we take 2733 away from 3120, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 14:
911 can be fit into 3870 4 times, resulting in a remainder of 226.
Use 4 as the next digit of our solution. 
Result so far: 78660.840834
Subtract 3644 from 3870 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 15:
911 goes into 2260 2 times with a remainder of 438.
The number 2 becomes the next digit in our result. 
Result so far: 78660.8408342
Deduct 1822 from 2260 and we're left with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 16:
If we divide 4380 by 911, we get 4 and a remainder of 736.
Use 4 as the next digit of our solution. 
Result so far: 78660.84083424
Subtracting 3644 from 4380 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The final outcome is 78660.84083424, with a leftover of 7.36e-07.
