We're dividing 41730 by 90 
The aim is to understand the frequency of 90 in 41730.

Step 1:
4 divided by 90 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 90

Step 2:
When dividing 41 by 90, we get 0 with a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 41, we get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 90

Going ahead to step 3:
90 goes into 417 4 times with a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 360 from 417, we get 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 90

Advancing to step 4:
90 can be fit into 573 6 times, resulting in a remainder of 33.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 540 from 573 and we're left with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 90

Advancing to step 5:
90 can be fit into 330 3 times, resulting in a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 463.0
If we subtract 270 from 330, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 6:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 463.6
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
600 divided by 90 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 463.66
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 463.66 and a remainder of 0.06.
