287622 divided by 17 
The aim is to understand the frequency of 17 in 287622.

On to step 1:
17 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 17

Let's proceed to step 2:
28 divided by 17 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 17 from 28 and we're left with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 17

Moving on to step 3:
117 divided by 17 is 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 15 after subtracting 102 from 117.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 17

Moving on to step 4:
When dividing 156 by 17, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 169.0
If we take 153 away from 156, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 17

Advancing to step 5:
When dividing 32 by 17, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1691.0
Subtract 17 from 32 to get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 17

Moving on to step 6:
17 can be fit into 152 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 16918.0
Deduct 136 from 152 and we're left 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 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: 16918.9
Subtracting 153 from 160 leaves us 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.

Going ahead to step 8:
If we divide 70 by 17, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 16918.94
If we subtract 68 from 70, we get 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 9:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 16918.941
If we subtract 17 from 20, we 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.

Step 10:
When dividing 30 by 17, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 16918.9411
If we subtract 17 from 30, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 16918.9411, and the remainder is 0.00013.
