We look at the division of 383989 by 35 
The aim is to understand the frequency of 35 in 383989.

Advancing to step 1:
When dividing 3 by 35, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 35

On to step 2:
The number 35 fits into 38 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 35 from 38 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 35

Step 3:
33 divided by 35 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 35

Advancing to step 4:
When dividing 339 by 35, we get 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Subtracting 315 from 339 leaves us with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 35

Going ahead to step 5:
35 goes into 248 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 1097.0
If we subtract 245 from 248, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 35

Advancing to step 6:
35 can be fit into 39 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 10971.0
Subtracting 35 from 39 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 35, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 10971.1
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 35, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 10971.11
Subtracting 35 from 50 leaves us 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.

Our division results in 10971.11 with a remaining 0.015.
