We're dividing 30391459 by 35 
The aim is to understand the frequency of 35 in 30391459.

Let's proceed to step 1:
When dividing 3 by 35, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 35

On to step 2:
The number 35 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 35

Let's proceed to step 3:
When dividing 303 by 35, we get 8 with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 280 from 303, we get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 35

Moving on to step 4:
When dividing 239 by 35, we get 6 with a remainder of 29.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 210 from 239 and we're left with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 35

Step 5:
35 goes into 291 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 868.0
If we subtract 280 from 291, we get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 35

Going ahead to step 6:
35 goes into 114 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 8683.0
If we take 105 away from 114, we end up with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 35

Advancing to step 7:
When dividing 95 by 35, we get 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 86832.0
Deduct 70 from 95 and we're left with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 35

Let's proceed to step 8:
If we divide 259 by 35, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 868327.0
Subtracting 245 from 259 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.

Step 9:
The number 35 fits into 140 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 868327.4
The remainder is 0 after subtracting 140 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 35 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 868327.4
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 35 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 868327.4
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 868327.4 with a remainder of 0.0.
