We look at the division of 46256 by 90 
The aim is to understand the frequency of 90 in 46256.

Advancing to step 1:
90 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 90

On to step 2:
If we divide 46 by 90, we get 0 and a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 90

Step 3:
90 can be fit into 462 5 times, resulting in a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 450 from 462, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 90

Step 4:
90 goes into 125 1 times with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 90 from 125 to get 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 90

Advancing to step 5:
If we divide 356 by 90, we get 3 and a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 513.0
If we subtract 270 from 356, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 6:
When dividing 860 by 90, we get 9 with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 513.9
Deduct 810 from 860 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
If we divide 500 by 90, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 513.95
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
If we divide 500 by 90, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 513.955
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 513.955 and a remainder of 0.005.
