We're dividing 286209 by 34 
The aim is to understand the frequency of 34 in 286209.

On to step 1:
The number 34 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 34

Going ahead to step 2:
If we divide 28 by 34, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 34

Going ahead to step 3:
34 can be fit into 286 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 272 from 286 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 34

Advancing to step 4:
The number 34 fits into 142 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we take 136 away from 142, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 34

Going ahead to step 5:
If we divide 60 by 34, we get 1 and a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 841.0
If we subtract 34 from 60, we get 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 34

Step 6:
269 divided by 34 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 8417.0
Subtracting 238 from 269 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
34 goes into 310 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 8417.9
Subtracting 306 from 310 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.

Step 8:
34 can be fit into 40 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 8417.91
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
60 divided by 34 is 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 8417.911
If we take 34 away from 60, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 8417.911 with a remaining 0.0026.
