We look at the division of 254648 by 17 
The aim is to understand the frequency of 17 in 254648.

Going ahead to step 1:
If we divide 2 by 17, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 17

Going ahead to step 2:
17 goes into 25 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 17 from 25 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 17

Moving on to step 3:
84 divided by 17 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 68 away from 84, we end up with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 17

Moving on to step 4:
When dividing 166 by 17, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
If we take 153 away from 166, we end up with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 17

Step 5:
The number 17 fits into 134 7 times, leaving a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 1497.0
Deduct 119 from 134 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 17

Step 6:
The number 17 fits into 158 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 14979.0
If we subtract 153 from 158, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
The number 17 fits into 50 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 14979.2
If we take 34 away from 50, we end up with 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 8:
17 can be fit into 160 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 14979.29
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.

Advancing to step 9:
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: 14979.294
Deduct 68 from 70 and we're left 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.

Going ahead to step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 14979.2941
The remainder is 3 after subtracting 17 from 20.
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 11:
When dividing 30 by 17, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 14979.29411
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.

After the division, we end up with 14979.29411 and a remainder of 1.3e-05.
