We're dividing 17402 by 34 
The aim is to understand the frequency of 34 in 17402.

On to step 1:
34 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 34

Step 2:
34 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 34

Advancing to step 3:
The number 34 fits into 174 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 170 from 174 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 34

On to step 4:
If we divide 40 by 34, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we take 34 away from 40, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 34

Going ahead to step 5:
The number 34 fits into 62 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 511.0
Subtracting 34 from 62 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 6:
The number 34 fits into 280 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 511.8
If we subtract 272 from 280, 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.

Going ahead to step 7:
34 can be fit into 80 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 511.82
Deduct 68 from 80 and we're left 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.

Advancing to step 8:
34 can be fit into 120 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 511.823
If we take 102 away from 120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
34 can be fit into 180 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 511.8235
The remainder is 10 after subtracting 170 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 34 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 511.82352
Deduct 68 from 100 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
34 can be fit into 320 9 times, resulting in a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 511.823529
The remainder is 14 after subtracting 306 from 320.
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 12:
34 goes into 140 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 511.8235294
Subtract 136 from 140 to get 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 13:
If we divide 40 by 34, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 511.82352941
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.

After the division, we end up with 511.82352941 and a remainder of 6e-09.
