Let's divide 35485 by 42
The aim is to understand the frequency of 42 in 35485.

Moving on to step 1:
42 can be fit into 3 0 times, resulting in 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.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 42

Advancing to step 2:
When dividing 35 by 42, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 42

Step 3:
42 can be fit into 354 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 336 away from 354, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 42

Moving on to step 4:
42 can be fit into 188 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 168 from 188 leaves us with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 42

Going ahead to step 5:
42 goes into 205 4 times with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 844.0
Subtracting 168 from 205 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 6:
42 goes into 370 8 times with a remainder of 34.
The next digit of our result is 8. 
Result so far: 844.8
If we take 336 away from 370, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
If we divide 340 by 42, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 844.88
If we take 336 away from 340, we end up 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.

The final result is 844.88 with a remainder of 0.004.
