Let's divide 286310 by 17
The aim is to understand the frequency of 17 in 286310.

On to step 1:
The number 17 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 17

Let's proceed to step 2:
The number 17 fits into 28 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 17 from 28 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 17

Going ahead to step 3:
When dividing 116 by 17, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 102 from 116 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 17

Advancing to step 4:
If we divide 143 by 17, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Deduct 136 from 143 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 17

Step 5:
17 goes into 71 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1684.0
Deduct 68 from 71 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 17

Going ahead to step 6:
If we divide 30 by 17, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 16841.0
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.

Going ahead to step 7:
The number 17 fits into 130 7 times, leaving a remainder of 11.
The next digit of our result is 7. 
Result so far: 16841.7
Deduct 119 from 130 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
17 goes into 110 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 16841.76
If we subtract 102 from 110, we get 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 9:
If we divide 80 by 17, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 16841.764
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
17 can be fit into 120 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 16841.7647
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 11:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 16841.7647
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
100 divided by 17 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 16841.764705
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 13:
17 goes into 150 8 times with a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 16841.7647058
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.

On to step 14:
140 divided by 17 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 16841.76470588
Subtracting 136 from 140 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 16841.76470588 with a remainder of 4e-09.
