Let's divide 771566 by 17
The aim is to understand the frequency of 17 in 771566.

Going ahead to step 1:
The number 17 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 17

Moving on to step 2:
77 divided by 17 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 68 away from 77, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 17

On to step 3:
91 divided by 17 is 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 85 from 91 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 17

Advancing to step 4:
17 goes into 65 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 453.0
If we take 51 away from 65, we end up with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 17

On to step 5:
The number 17 fits into 146 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 4538.0
Subtract 136 from 146 to get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 17

Going ahead to step 6:
The number 17 fits into 106 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 45386.0
The remainder is 4 after subtracting 102 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 17, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 45386.2
Subtract 34 from 40 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 17 is 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 45386.23
If we take 51 away from 60, 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.

Step 9:
If we divide 90 by 17, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 45386.235
Subtracting 85 from 90 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
When dividing 50 by 17, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 45386.2352
The remainder is 16 after subtracting 34 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 45386.23529
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 45386.235294
If we take 68 away from 70, 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.

Advancing to step 13:
When dividing 20 by 17, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 45386.2352941
Subtract 17 from 20 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 14:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 45386.23529411
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 45386.23529411 with a remainder of 1.3e-08.
