We're dividing 640243 by 34 
The aim is to understand the frequency of 34 in 640243.

Advancing to step 1:
6 divided by 34 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 34

Step 2:
When dividing 64 by 34, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 34 from 64, we get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 34

Going ahead to step 3:
If we divide 300 by 34, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 272 from 300 and we're left with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 34

On to step 4:
282 divided by 34 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Subtracting 272 from 282 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 34

Moving on to step 5:
34 can be fit into 104 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 1883.0
If we take 102 away from 104, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 34

Going ahead to step 6:
The number 34 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 18830.0
The remainder is 23 after subtracting 0 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 34 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 18830.6
Subtract 204 from 230 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
The number 34 fits into 260 7 times, leaving a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 18830.67
The remainder is 22 after subtracting 238 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
If we divide 220 by 34, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 18830.676
Subtracting 204 from 220 leaves us 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 10:
If we divide 160 by 34, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 18830.6764
The remainder is 24 after subtracting 136 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
34 goes into 240 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 18830.67647
If we take 238 away from 240, we end up 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.

Let's proceed to step 12:
If we divide 20 by 34, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 18830.67647
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
When dividing 200 by 34, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 18830.6764705
The remainder is 30 after subtracting 170 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
The number 34 fits into 300 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 18830.67647058
Subtracting 272 from 300 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.

In conclusion, the division gives 18830.67647058 with a balance of 2.8e-08.
