We look at the division of 660220 by 34 
The aim is to understand the frequency of 34 in 660220.

Moving on to step 1:
When dividing 6 by 34, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 34

Let's proceed to step 2:
34 goes into 66 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 34 from 66, we get 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 34

On to step 3:
34 goes into 320 9 times with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 306 from 320, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 34

Advancing to step 4:
If we divide 142 by 34, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 194.0
Subtracting 136 from 142 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 34

Step 5:
34 can be fit into 62 1 times, resulting in a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1941.0
If we subtract 34 from 62, we get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 34

Let's proceed to step 6:
34 goes into 280 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 19418.0
If we take 272 away from 280, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
80 divided by 34 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 19418.2
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
If we divide 120 by 34, we get 3 and a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 19418.23
The remainder is 18 after subtracting 102 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
34 goes into 180 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 19418.235
Subtract 170 from 180 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
34 can be fit into 100 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 19418.2352
If we take 68 away from 100, we end up 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.

On to step 11:
320 divided by 34 is 9 with a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 19418.23529
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.

Let's proceed to step 12:
34 can be fit into 140 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 19418.235294
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
34 can be fit into 40 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 19418.2352941
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.

On to step 14:
The number 34 fits into 60 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 19418.23529411
Subtract 34 from 60 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.

The final result is 19418.23529411 with a remainder of 2.6e-08.
