We look at the division of 237574 by 17 
The aim is to understand the frequency of 17 in 237574.

Let's proceed to step 1:
17 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 17

Step 2:
When dividing 23 by 17, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 17 from 23 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 17

Let's proceed to step 3:
If we divide 67 by 17, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 51 away from 67, we end up with 16.
Include the next digit (5) from the dividend after 16, then repeat: 165 / 17

Moving on to step 4:
The number 17 fits into 165 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we subtract 153 from 165, we get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 17

On to step 5:
The number 17 fits into 127 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 1397.0
If we take 119 away from 127, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 17

Going ahead to step 6:
84 divided by 17 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 13974.0
If we subtract 68 from 84, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 17, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 13974.9
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 13974.94
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
When dividing 20 by 17, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 13974.941
Subtracting 17 from 20 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.

On to step 10:
If we divide 30 by 17, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 13974.9411
Subtracting 17 from 30 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 13974.9411 and a remainder of 0.00013.
