We look at the division of 508900 by 35 
The aim is to understand the frequency of 35 in 508900.

Going ahead to step 1:
5 divided by 35 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 35

On to step 2:
50 divided by 35 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 35 away from 50, we end up with 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 35

Advancing to step 3:
35 goes into 158 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 140 from 158 leaves us with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 35

On to step 4:
When dividing 189 by 35, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 145.0
If we subtract 175 from 189, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 35

Advancing to step 5:
140 divided by 35 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 1454.0
Subtract 140 from 140 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 35

Step 6:
35 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14540.0
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.

Let's proceed to step 7:
If we divide 0 by 35, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14540.0
Subtracting 0 from 0 leaves us 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 8:
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: 14540.0
If we subtract 0 from 0, we get 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 outcome is 14540.0, with a leftover of 0.0.
