We look at the division of 90308621 by 467 
The aim is to understand the frequency of 467 in 90308621.

Moving on to step 1:
467 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 467

Step 2:
467 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Take the next digit (3) from the dividend and append it to 90, then repeat: 903 / 467

Going ahead to step 3:
903 divided by 467 is 1 with a remainder of 436.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 467 from 903 leaves us with 436.
Include the next digit (0) from the dividend after 436, then repeat: 4360 / 467

On to step 4:
467 can be fit into 4360 9 times, resulting in a remainder of 157.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 157 after subtracting 4203 from 4360.
Append the next digit (8) from the dividend to 157 and continue with: 1578 / 467

Going ahead to step 5:
467 goes into 1578 3 times with a remainder of 177.
Use 3 as the next digit of our solution. 
Result so far: 193.0
The remainder is 177 after subtracting 1401 from 1578.
Bring next digit (6) of the dividend behind the 177 and repeat the process: 1776 / 467

Let's proceed to step 6:
The number 467 fits into 1776 3 times, leaving a remainder of 375.
The number 3 becomes the next digit in our result. 
Result so far: 1933.0
Subtracting 1401 from 1776 leaves us with 375.
Include the next digit (2) from the dividend after 375, then repeat: 3752 / 467

Advancing to step 7:
When dividing 3752 by 467, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 19338.0
If we subtract 3736 from 3752, we get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 467

Advancing to step 8:
161 divided by 467 is 0 with a remainder of 161.
The number 0 becomes the next digit in our result. 
Result so far: 193380.0
The remainder is 161 after subtracting 0 from 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Let's proceed to step 9:
When dividing 1610 by 467, we get 3 with a remainder of 209.
The number 3 becomes the next digit in our result. 
Result so far: 193380.3
If we take 1401 away from 1610, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 10:
467 can be fit into 2090 4 times, resulting in a remainder of 222.
Write down 4 as next digit of the result. 
Result so far: 193380.34
Subtract 1868 from 2090 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 11:
467 can be fit into 2220 4 times, resulting in a remainder of 352.
Put 4 as the next digit of the answer. 
Result so far: 193380.344
The remainder is 352 after subtracting 1868 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 193380.344 and a remainder of 0.0352.
