We're dividing 342035 by 90 
The aim is to understand the frequency of 90 in 342035.

Moving on to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 90

Step 2:
When dividing 34 by 90, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 90

Advancing to step 3:
90 goes into 342 3 times with a remainder of 72.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 270 from 342, we get 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 90

Going ahead to step 4:
720 divided by 90 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 720 from 720 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 90

Step 5:
If we divide 3 by 90, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 380.0
Subtract 0 from 3 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 90

Going ahead to step 6:
90 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 3800.0
Subtract 0 from 35 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
If we divide 350 by 90, we get 3 and a remainder of 80.
The next digit of our result is 3. 
Result so far: 3800.3
Subtract 270 from 350 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 8:
90 goes into 800 8 times with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 3800.38
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
If we divide 800 by 90, we get 8 and a remainder of 80.
The next digit of our result is 8. 
Result so far: 3800.388
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 3800.388 with a remaining 0.008.
