433575 ÷ 35 
The aim is to understand the frequency of 35 in 433575.

Moving on to step 1:
35 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 35

Step 2:
43 divided by 35 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 35 from 43 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 35

Moving on to step 3:
The number 35 fits into 83 2 times, leaving a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 70 from 83 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 35

On to step 4:
135 divided by 35 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Subtract 105 from 135 to get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 35

On to step 5:
35 goes into 307 8 times with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 1238.0
If we take 280 away from 307, we end up with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 35

On to step 6:
35 can be fit into 275 7 times, resulting in a remainder of 30.
The next digit of our result is 7. 
Result so far: 12387.0
Subtracting 245 from 275 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
When dividing 300 by 35, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 12387.8
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 35 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 12387.85
Subtract 175 from 200 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
35 can be fit into 250 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 12387.857
The remainder is 5 after subtracting 245 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
The number 35 fits into 50 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 12387.8571
Deduct 35 from 50 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
When dividing 150 by 35, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 12387.85714
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 35, we get 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 12387.857142
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
35 can be fit into 300 8 times, resulting in a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 12387.8571428
Subtract 280 from 300 to get 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 14:
If we divide 200 by 35, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 12387.85714285
Subtracting 175 from 200 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 12387.85714285, with a leftover of 2.5e-08.
