We look at the division of 949543 by 17 
The aim is to understand the frequency of 17 in 949543.

Advancing to step 1:
The number 17 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 17

Going ahead to step 2:
17 can be fit into 94 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 85 from 94 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 17

Going ahead to step 3:
The number 17 fits into 99 5 times, leaving a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we subtract 85 from 99, we get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 17

On to step 4:
The number 17 fits into 145 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 558.0
If we take 136 away from 145, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 17

Going ahead to step 5:
17 goes into 94 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5585.0
Subtract 85 from 94 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 17

On to step 6:
When dividing 93 by 17, we get 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 55855.0
If we take 85 away from 93, 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.

Step 7:
When dividing 80 by 17, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 55855.4
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 17, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 55855.47
If we take 119 away from 120, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
The number 17 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 55855.47
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
17 can be fit into 100 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 55855.4705
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
When dividing 150 by 17, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 55855.47058
Subtracting 136 from 150 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 55855.470588
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 55855.470588 with a remaining 4e-07.
