Let's divide 366675 by 90
The aim is to understand the frequency of 90 in 366675.

Let's proceed to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 90

Let's proceed to step 2:
36 divided by 90 is 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Bring next digit (6) of the dividend behind the 36 and repeat the process: 366 / 90

On to step 3:
The number 90 fits into 366 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 360 from 366, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 90

Let's proceed to step 4:
If we divide 66 by 90, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 90

Step 5:
667 divided by 90 is 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 407.0
If we take 630 away from 667, we end up with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 90

Advancing to step 6:
When dividing 375 by 90, we get 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 4074.0
Deduct 360 from 375 and we're left 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.

On to step 7:
150 divided by 90 is 1 with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 4074.1
Subtracting 90 from 150 leaves us 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.

On to step 8:
If we divide 600 by 90, we get 6 and a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4074.16
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.

Let's proceed to step 9:
90 goes into 600 6 times with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4074.166
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.

Our division results in 4074.166 with a remaining 0.006.
