343035 ÷ 90 
The aim is to understand the frequency of 90 in 343035.

On to step 1:
90 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
Deduct 0 from 3 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 90

Let's proceed to step 2:
90 can be fit into 34 0 times, resulting in a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 90

Moving on to step 3:
When dividing 343 by 90, we get 3 with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 270 from 343 leaves us with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 90

Let's proceed to step 4:
90 can be fit into 730 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtract 720 from 730 to get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 90

Moving on to step 5:
When dividing 103 by 90, we get 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 381.0
The remainder is 13 after subtracting 90 from 103.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 90

Advancing to step 6:
The number 90 fits into 135 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 3811.0
If we take 90 away from 135, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
When dividing 450 by 90, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3811.5
Subtracting 450 from 450 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:
90 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3811.5
Subtract 0 from 0 to 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.

Step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3811.5
Subtract 0 from 0 to 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 result is 3811.5 with a remainder of 0.0.
