We divide 147665 by 90
The aim is to understand the frequency of 90 in 147665.

Moving on to step 1:
When dividing 1 by 90, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 90

Moving on to step 2:
The number 90 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 90

On to step 3:
90 can be fit into 147 1 times, resulting in a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 57 after subtracting 90 from 147.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 90

Moving on to step 4:
If we divide 576 by 90, we get 6 and a remainder of 36.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 540 from 576 and we're left with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 90

On to step 5:
When dividing 366 by 90, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we take 360 away from 366, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 90

On to step 6:
The number 90 fits into 65 0 times, leaving a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 1640.0
Subtracting 0 from 65 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
When dividing 650 by 90, we get 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 1640.7
The remainder is 20 after subtracting 630 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
90 goes into 200 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1640.72
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 90 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1640.722
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 1640.722 with a remaining 0.002.
