We look at the division of 90210509 by 162 
The aim is to understand the frequency of 162 in 90210509.

Step 1:
The number 162 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 162

Let's proceed to step 2:
The number 162 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 162

Step 3:
If we divide 902 by 162, we get 5 and a remainder of 92.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 810 from 902 leaves us with 92.
Bring next digit (1) of the dividend behind the 92 and repeat the process: 921 / 162

On to step 4:
921 divided by 162 is 5 with a remainder of 111.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtracting 810 from 921 leaves us with 111.
Bring next digit (0) of the dividend behind the 111 and repeat the process: 1110 / 162

Going ahead to step 5:
The number 162 fits into 1110 6 times, leaving a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 556.0
Subtracting 972 from 1110 leaves us with 138.
Append the next digit (5) from the dividend to 138 and continue with: 1385 / 162

Going ahead to step 6:
When dividing 1385 by 162, we get 8 with a remainder of 89.
Put 8 as the next digit of the answer. 
Result so far: 5568.0
If we take 1296 away from 1385, we end up with 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 162

Moving on to step 7:
162 goes into 890 5 times with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 55685.0
If we take 810 away from 890, we end up with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 162

Advancing to step 8:
162 goes into 809 4 times with a remainder of 161.
Record the quotient 4 as the next digit in the result. 
Result so far: 556854.0
Subtract 648 from 809 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 9:
If we divide 1610 by 162, we get 9 and a remainder of 152.
Write down 9 as next digit of the result. 
Result so far: 556854.9
The remainder is 152 after subtracting 1458 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
1520 divided by 162 is 9 with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 556854.99
Subtracting 1458 from 1520 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 556854.99 with a balance of 0.062.
