151828 divided by 90 
The aim is to understand the frequency of 90 in 151828.

Advancing to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 90

On to step 2:
15 divided by 90 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 90

On to step 3:
90 goes into 151 1 times with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 61 after subtracting 90 from 151.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 90

Moving on to step 4:
When dividing 618 by 90, we get 6 with a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 540 from 618 to get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 90

Let's proceed to step 5:
782 divided by 90 is 8 with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 168.0
If we take 720 away from 782, we end up with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 90

Let's proceed to step 6:
The number 90 fits into 628 6 times, leaving a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 1686.0
If we take 540 away from 628, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 7:
The number 90 fits into 880 9 times, leaving a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 1686.9
Subtracting 810 from 880 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 1686.97
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 9:
700 divided by 90 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 1686.977
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 1686.977 with a balance of 0.007.
